`OPTICAL STORAGE DEVICE
`
`RELATED APPLICATION
`
`This application claims the bene?t of US. Provisional
`Application No. 60/051,999, ?led Jul. 9, 1997.
`
`BACKGROUND
`
`The present invention relates generally to audio recording
`devices, and relates speci?cally to a novel recording device
`for recording onto a compact disc or other optical storage
`media.
`Present audio tape recorder/players provide for both audio
`recording onto a cassette tape and play back of the audio
`recording, and are generally relatively easy to use. The
`typical audio tape recorder/player has several push-buttons
`Which alloW a user to have the device perform a number of
`functions in connection With the cassette tape. Normally, a
`push-button is provided for each of the folloWing functions:
`pause, stop, reWind, fast forWard, play and record.
`In addition to being easy to use, some audio tape recorder/
`players provide additional advantages by Way of advanced
`features. For example, some provide that one can determine
`a recording sound level before or during a recording, and set
`or adjust a recording gain level in response thereto.
`Speci?cally, some provide a digital display, such as an LED
`display, that indicates the sound level Which Will be recorded
`(or Which is being recorded) onto the cassette tape, and
`provide a rotary knob, or other type of adjustor, Which one
`can adjust in order to set (or adjust) the recording gain level.
`HoWever, even these more advanced audio tape recorder/
`players do not provide that one can listen to hoW the
`recording actually sounds until after the sounds are recorded
`onto the tape. In other Words, the typical audio tape recorder/
`player does not alloW one to truly “audition” a recording
`before it is actually recorded onto a cassette tape. As a result,
`several “takes” may be required before an acceptable record
`ing is obtained. A recording may be unacceptable because of
`a number of reasons such as, for example, because the
`recording gain level Was set too loW or too high.
`Additionally, present audio tape recorder/players do not
`provide an easy Way to vary the order in Which a set of
`sounds, such as a set of songs, Will appear on the cassette
`tape. Because an audio tape recorder/player records essen
`tially What it “hears” or receives, in real time, it is not
`possible to easily customiZe the order in Which sound tracks,
`such as songs, Will appear on the recorded tape.
`Another disadvantage of audio tape recorder/players is
`that they produce analog recordings, and analog recordings
`have a loWer sound quality than do digital recordings.
`Furthermore, cassette tapes are not as durable as compact
`discs. For example, a dirty tape head may effectively destroy
`a cassette tape upon play back. For these reasons, cassette
`tapes are no longer the standard in the music industry, and
`compact discs are noW en vogue. Therefore, While the
`demand for audio tape recorder/players has decreased, the
`demand for compact disc players has been increasing.
`Like present audio tape recorder/players, present compact
`disc players are also relatively easy to use and provide
`push-button controls, With a push-button being provided for
`each of the folloWing functions in connection With the
`compact disc: pause, stop, track reverse, track forWard and
`play. The track reverse and track forWard functions of the
`present-day compact disc player are much like the reWind
`and forWard functions, respectively, of the present-day audio
`tape recorder/player. HoWever, the nature of compact discs
`
`10
`
`15
`
`25
`
`35
`
`45
`
`55
`
`65
`
`2
`provides that the track reverse and track forWard functions
`of a compact disc player are more useful than the respective
`reWind and fast forWard functions of an audio tape recorder/
`player. Speci?cally, holding the track reverse or track for
`Ward push-button doWn provides that the compact disc
`player skips back or forWard, respectively, Within a given
`sound track. In contrast, tapping the track reverse or track
`forWard push-button on the compact disc player provides
`that the compact disc player very quickly skips back or
`ahead, respectively, to the previous or next sound track on
`the compact disc. Because of the general nature of cassette
`tapes, this latter feature cannot effectively be provided on
`audio tape recorder/players.
`As mentioned, compact disc players provide certain
`advantages over audio tape players. Compact disc players
`play back digital sound recordings from a compact disc, and
`digital sound recordings have a higher sound quality than do
`analog signal recordings. Also, compact disc players provide
`for fast movement to the previous or next sound track.
`HoWever, While audio tape recorder/players provide that one
`can record onto a cassette tape, most presently generally
`available compact disc players do not provide that one can
`record onto a compact disc.
`Those compact disc recorders Which are generally avail
`able record onto a compact disc in real time and do not
`provide any true editing functions. For example, some
`compact disc recorders noW available provide that a source
`device, such as a compact disc player or a cassette tape
`player, is ?rst connected to inputs of the compact disc
`recorder. Then, as the source device is operated to begin
`playing music from the source medium, the compact disc
`recorder is operated to begin recording. Therefore, as the
`source device is playing music, the compact disc recorder
`records the music in real time, as the compact disc recorder
`receives the music through its inputs.
`There are many disadvantages to having to record in real
`time. One disadvantage is that editing is severely limited. If
`a mistake is made, the mistake is generally non-correctable.
`For example, if one begins recording the Wrong song onto
`the compact disc or begins recording a song at the Wrong
`volume, the mistake cannot readily be corrected. One Would
`have to start over, and begin recording onto a neW compact
`disc. Another disadvantage to having to record in real time
`is that if one Wishes to make several identical compact discs,
`one Would need to re-play all of the source music into the
`compact disc recorder. Of course, this effectively provides
`more opportunities for mistakes to be made While recording.
`Furthermore, if one Wishes to make a second compact disc
`much like a compact disc Which Was made previously, With
`the exception of one song being replaced by another, one
`Would need to re-play all of the previous source music into
`the compact disc recorder in addition to having to play the
`neW song into the recorder. LikeWise, if one Wishes to make
`a second compact disc much like a compact disc Which Was
`made previously, With the exception of the songs on the
`second compact disc appearing in a different sequence, one
`Would need to re-play all of the previous source music into
`the compact disc recorder, albeit in a different order.
`Some other compact disc recorders noW available include
`tWo compact disc trays—one tray for playing music from a
`compact disc, and one tray for recording the music onto
`another compact disc. In other Words, music is recorded
`from tray-to-tray. This type of compact disc recorder pre
`sents many of the same disadvantages as discussed above
`because the recording is still done in real time.
`Most of the compact disc recorders presently available
`can play music from a standard compact disc, thereby

`operating like a standard compact disc player. However, the
`devices generally cannot play back music Which Was
`received previously by the device unless the compact disc
`containing that music is ?rst inserted into the tray of the
`device.
`Another disadvantage to the compact disc recorders
`Which are presently generally available is that the devices
`cannot be used to record onto standard CD-R discs Which
`can be played back using any standard compact disc player.
`Standard CD-R recordable compact discs (as opposed to
`discs marked “for consumer use”) are presently Widely
`available, are inexpensive, and can be played back using any
`standard compact disc player.
`The present invention is directed at solving the disadvan
`tages discussed hereinabove.
`
`OBJECTS AND SUMMARY OF THE
`DRAWINGS
`
`A general object of the present invention is to provide a
`compact disc recorder Which provides advantages not gen
`erally provided by other presently available compact disc
`recorders.
`Another object of the present invention is to provide a
`compact disc recorder Which can be used to store music
`tracks as easily as using a modern-day audio tape recorder/
`player.
`A further object of the present invention is to provide a
`compact disc recorder that provides that one can listen to a
`stored sound track before the sound track is recorded onto a
`compact disc (i.e. truly “audition” a recording).
`Still another object of the present invention is to provide
`a compact disc recorder that provides that one can easily
`customiZe the order in Which sound tracks Will appear on a
`compact disc.
`Yet still another object of the present invention is to
`provide a compact disc recorder that can play back music
`Which Was received previously by the recorder Without a
`compact disc containing that music being ?rst inserted into
`the device.
`Yet a further object of the present invention is to provide
`a compact disc recorder that can be used to record onto
`computer-compatible compact discs Which are presently
`Widely available, are inexpensive, and can be played back
`using a standard compact disc player.
`Brie?y, and in accordance With at least one of the fore
`going objects, the present invention envisions an optical
`storage medium recorder, such as a compact disc recorder,
`Which includes sound receiving means for receiving analog
`signals, a convertor connected to the sound receiving means
`for converting the received analog signals into digital data,
`data storage structure communicatingly connected to the
`convertor for receiving the digital data from the convertor
`and storing the digital data received, and an optical storage
`drive, such as a compact disc recordable drive, communi
`catingly connected to the data storage structure for receiving
`the stored digital data from the data storage structure and
`recording the digital data onto an optical storage medium,
`such as onto a compact disc, received by the optical storage
`drive.
`A preferred embodiment of the present invention envi
`sions a compact disc recorder embodied in a housing and
`including at least one analog line-in jack on the housing for
`receiving analog signals, an analog-to-digital convertor
`Within the housing connected to the at least one analog
`line-in jack for converting the analog signals received by the

`analog line-in jack into digital data, a central processing unit
`communicatingly connected to the analog-to-digital conver
`tor for receiving digital data, data storage structure commu
`nicatingly connected to the central processing unit for
`receiving digital data from the central processing unit and
`storing the digital data received, a digital-to-analog conver
`tor connected to the central processing unit for receiving
`digital data, a compact disc recordable drive communicat
`ingly connected to the central processing unit for receiving
`digital data stored in the data storage structure and for

`?gured for displaying information on the display device
`relating to sound tracks stored in the data storage device, and
`there are input keys on the housing communicatingly con
`nected to the central processing unit for manipulating the
`information displayed on the display device. The central
`processing unit is also con?gured so that at least one of the
`input keys can be operated to selectively store sound tracks
`in the data storage structure and so that at least one of the
`input keys can be used to selectively display a master song
`list and at least one session song list on the display device,
`Where the master song list lists all the sound tracks stored
`and available in the data storage structure, and the session
`song list lists a particular group of sound tracks Which Were
`previously selected to be in that particular session using at
`least one of the input keys. The central processing unit is
`also con?gured so that at least one of the input keys can be
`operated to output analog signals through the audio output
`structure relating to sound tracks previously stored in the
`data storage structure.
`Preferably, the central processing unit is also con?gured
`so that at least one of the input keys can be operated to
`perform at least one of the folloWing editing functions: to
`combine a plurality of stored sound tracks into a single
`stored sound track, to split a single stored sound track into
`a plurality of stored sound tracks, to trim a stored sound
`track, to convert a stored sound track so that the sound track
`has a different amplitude, and to convert a stored sound track
`so that the sound track either fades in or fades out. Still
`further, the central processing unit is also preferably con
`?gured so that at least one of the input keys can be operated
`to control play back of a compact disc received by the
`compact disc recordable drive.

`
`DESCRIPTION
`
`While the present invention may be susceptible to
`embodiment in different forms, there is shoWn in the
`draWings, and herein Will be described in detail, an embodi
`ment With the understanding that the present description is
`to be considered an eXempli?cation of the principles of the
`invention and is not intended to limit the invention to that as
`illustrated and described herein.
`ShoWn in FIG. 1 is an optical storage device or compact
`disc recorder 30 in accordance With an embodiment of the
`present invention. The compact disc recorder 30 is a easy
`to-use stand-alone audio recording device that can receive
`signals from an analog audio source and produce digital
`recordings onto a compact disc. As Will be described, the
`compact disc recorder 30 has memory so sound tracks can
`be stored therein and selectively played back. In this regard,
`the compact disc recorder 30 can be effectively employed as
`a modern-day juke boX. Additionally, the fact that the
`compact disc recorder 30 includes memory provides that
`saved sound tracks can be revieWed, or “auditioned”, before
`being burned onto a compact disc. Preferably, the compact
`disc recorder 30 has many enhanced functions alloWing for
`the advanced editing of stored sound tracks, and can be used
`to play back standard, commercially available compact
`discs. These advantages as Well as many others Will be
`apparent after reading the folloWing description of the
`compact disc recorder 30.
`Internal components of the compact disc recorder 30 are
`protected by a housing 32, Which may be a fabricated metal
`case much like those of standard stereo decks such as
`cassette decks and compact disc players. As shoWn in FIG.
`1, the housing 32 has a front panel 34, a back panel 36, sides
`38, a top 40 and a bottom 42. The housing 32 may
`incorporate, or have attached thereto, standard computer
`bay/mounting hardWare, such as rails for drive mounting,
`one or more slots for circuit board mounting, and other
`mounting attachment structure.
`As shoWn in FIGS. 1 and 2, the front panel 34 of the
`compact disc recorder 30 is an injection-molded front beZel
`44 Which provides, essentially, a user interface Which dis
`plays information to a user and provides means for alloWing
`the user to program and control the compact disc recorder
`30. The front beZel 44 has a digital graphic display device 46
`thereon. The digital graphic display unit 46 is, for eXample,
`a 240x64 dot graphics LCD With LED back-light, or may be
`a type of plasma display and/or a group of lamp devices.
`Regardless, the digital graphic display device 46 provides
`that the compact disc recorder 30 can communicate certain
`information to the user in connection With the operation,
`control and programming of the compact disc recorder 30.
`In addition, the digital graphic display unit 46 may also be
`a graphic user interface, such as a touch screen Whereby a
`user can operate, control and program the compact disc
`recorder 30 by physically touching the digital graphic dis
`play unit 46 With a ?nger, light pen, or some other object.
`The front beZel 44 also provides a means to give editing
`commands to embedded softWare (to be discussed later
`
`10
`

`herein) for ordering, auditioning and playing back sound
`tracks stored in the compact disc recorder 30, prior to
`recording the tracks onto a compact disc. Speci?cally, the
`front beZel 44 has a set 48 of siX transport control push
`buttons 41, 43, 45, 47, 49, 50 thereon for providing that the
`user can control the functioning of the compact disc recorder
`30. The set 48 of push-buttons are identical to those typically
`found on present-day compact disc players, but also includes
`a push-button to direct the compact disc recorder 30 to enter
`a record mode as Will be described more fully later. In other
`Words, there is a separate push-button provided for each of
`the folloWing functions of the compact disc recorder 30: stop
`(button 41), pause (button 43), reverse track (button 45),
`play (button 47), forWard track (button 49) and record
`(button 50). The front beZel 44 also includes a second set 52
`of siX push-buttons 53, 55, 57, 59, 61, 63 each of Which
`relates to certain functions of the compact disc recorder 30
`relating to programming the compact disc recorder 30 and
`editing sound tracks previously stored therein. Preferably,
`the second set 52 of push-buttons alloWs a user to access and
`interact With menus displayed on the digital graphic display
`device 46. This Will be described in more detail later herein.
`Preferably, both sets 48 and 52 of push-buttons on the front
`beZel are illuminated, such as by LEDs.
`The front beZel 44 also includes optical storage medium
`receiving structure so that an optical storage medium may be
`inserted into an optical storage drive. As shoWn, the optical
`storage medium receiving structure and optical storage drive
`may comprise a compact disc tray 54 and a compact disc
`tray eject/retract button 56 Where the compact disc tray 54
`forms a portion of a compact disc recordable drive 58 (see
`FIGS. 4 and 5) that is housed Within the housing 32 of the
`compact disc recorder 30. Pressing th
