`
`
`National foreword
`
`This British Standard is the English language version of EN 609081999. It is
`identical with IEC 60908:1999. It supersedes BS EN 60908: 1993 which will be
`withdrawn on 2001-11-01.
`
`The UK participation in its preparation was entrusted by Teclmical Committee
`EPL/100, Audio, Video and Multimedia Systems and Equipment, to Subcommittee
`EPL/100/2, Recording, which has the responsibility to:
`
`— aid enquirers to understand the text;
`
`- present to the responsible international/European committee any enquiries
`on the interpretation, or proposals for change, and keep the UK interests
`informed;
`
`— monitor related intemational and European developments and promulgate
`them in the UK.
`
`A list of organizations represented on this committee can be obtained on request to
`its secretary.
`
`From 1 January 1997, all [EC publications have the number 60000 added to the old
`number. For instance, IEC 27-1 has been renumbered as IEC 60027-1. For a period
`of time during the change over from one numbering system to the other,
`publications may contain identifiers from both systems.
`Cross-references
`
`Attention is drawn to the fact that CEN and CENELEC Standards normally include
`an annex which lists normative references to intemational publications with their
`corresponding European publications. The British Standards which implement
`intemational or European publications referred to in this document may be found in
`the BSI Standards Catalogue under the section entitled “International Standards
`Correspondence Index”, or by using the “Find” facility of the BSI Standards
`Electronic Catalogue.
`
`A British Standard does not purport to include all the necessary provisions of a
`contract Users of British Standards are responsible for their correct application.
`
`Compliance with a British Standard does not of itself confer immunity
`from legal obligations.
`
`This British Standard, having
`been prepared under the
`direction of the Electrotechnical
`Sector Committee, was published
`under the authority of the
`Standards Committee and comes
`into effect on

`amendment A2 to EN 60908:1992 on 1998-10-01.
`
`The text of this document, together with that of IEC 60908: 1 987 and its amendment 1:1992,

`The following dates were fixed:
`
`— latest date by which the EN has to be implemented
`at national level by publication of an identical
`national standard or by endorsement
`
`- latest date by which the national standards conflicting
`with the EN have to be withdrawn

`
`Endorsement notice
`

`
`AUDIO RECORDING -
`COMPACT DISC DIGITAL AUDIO SYSTEM —
`
`1 Scope and object
`
`This standard is applicable to a prerecorded optical reflective digital audio disc system.
`
`- This standard defines those parameters of compact disc that affect interchangeability between
`discs and players. It is also intended as a reference for manufacturers wishing to produce discs
`and/or players that conform to the system described in this standard.
`It deals with discs of
`80 mm in diameter as well as those of 120 mm in diameter.
`
`2 Normative references
`
`The following normative documents contain provisions which, through reference in this text,
`constitute provisions of
`this
`international Standard. For dated references,
`subsequent
`amendments to. or revisions of. any of these publications do not apply. However. parties to
`agreements based on this international Standard are encouraged to investigate the possibility
`of applying the most recent editions of the normative documents indicated below. For undated
`references. the latest edition of the normative document referred to applies. Members of IEC
`and lS0 maintain registers of currently valid International Standards.

`
`11 Defects
`
`1 1.1 Block error rate (BLEH)
`
`11.1.1 Definitions
`
`The block error rate is measured at the input of the C1-decoder (see figure 13).
`
`A block (see figure 9) is called erroneous it one or more symbols of that block are erroneous.
`
`A symbol (see 16.2) is called erroneous if one or more bits of that symbol are erroneous.
`
`11.1.2 Specification of random errors
`
`BLEE averaged over any 16 s shaii be less than 3 x 1-.'.‘r*'=‘.
`
`11.1.3 Specification of burst errors
`
`Burst errors in the M. signal due to local detects shall not induce audible effects for any error-
`correcting decoding strategy.
`
`The most simple error-correcting decoder consists of a C1 and C2 single-error corrector. No
`more than one symbol error shall occur in a data block measured at the input of the C2
`decoder.
`
`In any case. the number of successive C1-uncorrectable blocks shall be less than 7.
`
`11.2 Local defects
`
`Maximum dimensions of local defects that are allowed are:
`
`- air bubbles, diameter
`
`— black spots, diameter
`
`-
`
`black spots without birefringent area, diameter
`
`100 pm
`
`200 pm
`
`300 um
`
`The minimum distance, measured between adjacent defects (of maximum diameter) along the
`track, is at least 20 mm.
`
`Black spot may be dirt enclosures in the substrate or "pin-holes" in the reflective layer.
`
`12 Recorded parameters - General
`
`The recorded area on the disc shall be divided into three parts, viz:
`
`—
`
`the lead-in area;
`
`— the program area;
`— the lead-out area.
`
`The data to be recorded shall consist of 16~bits wide words encoded as 2's-complement
`numbers.
`
`Page 00006
`
`

`
`Page 15
`EN 60908:1999
`
`In the lead-in and the lead—out areas these encoded words are 2's-complement zero :15 LSB.
`
`In the program area the data word contains audio information only, encoded in a two-channel
`format.
`
`The sampling frequency (fs) of the information in the program area shall be 44,1 kHz, both
`channels being simultaneously sampled.
`
`The audio samples are linear encoded in a 16-bit, 2's-complement format.
`
`The encoding is carried out either without pre-emphasis or with the first order pre-emphasis
`shown in figure 1.
`.
`
`The recording and error protection process basically consists of
`
`a)
`b)
`
`splitting each 16-bit audio sample word into two B-bit symbols;
`introducing extra B-bit parity symbols for error detection and correction (in accordance with
`CIRC encoding);
`
`c) building up a frame consisting of the previously defined 8-bit symbols, with one 8-bit symbol
`for control and display;
`
`d)
`
`representing these 8-bit symbols by particular channel bit sequences which are appropriate
`for recording on the disc (in accordance with the EFM encoding);
`e) adding specific synchronization patterns different from EFM-codes.
`
`13 8 to 14 modulation code (EFM-code)
`
`After modulation, each group of 8 data bits (symbol) is represented by a succession of 14
`channel bits. The information is contained in the position of the transitions between channel
`bits.
`
`In the NFIZ-I
`in accordance with figure 6 and figure 7.
`The EFM encoding is carried out
`representation used to describe the EFM encoding, "0" indicates the absense of transitions
`between two successive channel bits whereas "1' indicates the presence of transitions.
`
`For merging the blocks and for low-frequency (l.f.) suppression,
`(merging bits) are added between two blocks of 14 channel bits.
`
`three extra channel bits
`
`Minimum requirements for Lt. suppression are under consideration.
`
`The EFM-code is such that the minimum run length (the distance between two transitions) is
`3 channel bits (T,,,;,,_) and the sampling window (eye pattern) is 1 channel bit.
`
`The maximum length is 11 channel bits (Tmfl).
`
`The merging bits do not need to contain a transition, so that between the blocks the
`requirements for T,,.in_ can always be fulfilled.
`
`Examples for the combination of the EFM-code with the merging bits are given in annex A.
