`DETAILED DESCRIPTION
`
`[Detailed Description of the Invention]
`[0001]
`[Industrial Application]The present invention relates to the personal computer system containing
`two or more personal computers and two or more magnetic disk drives.
`[0002]
`[Description of the Prior Art]Conventionally, only one physical magnetic disk drive can respond to
`one logic magnetic disk drive, but the magnetic-disk management of upper level software (operating
`system) of the magnetic disk controler in a personal computer system is also the same.
`[0O03]A magnetic disk drive was not able to be shared with two or more personal computers.
`[0004]
`[Problem to be solved by the invention]Since the conventional magnetic disk controler mentioned
`above serves as specification to which only one physical magnetic disk drive can be equivalent to
`one logic magnetic disk drive, The fault that there is a fault that the data exceeding the capacity of
`one magnetic disk drive cannot be carried, and a magnetic disk drive cannot be shared with two or
`more personal computers is ****.
`[00O5]The object of this invention by accessing all the storage areas of two or more magnetic disk
`drives from each personal computer as a storage area of one magnetic disk drive, While making it
`possible to treat the data of the size exceeding the capacity of one magnetic disk drive, It is
`providing the microcomputer system which has a magnetic disk controler which can share two or
`more magnetic disk drives with two or more microcomputers, managing the access right of each
`personal computer.
`[0006]
`[Means for solving prob|em]The personal computer system of the present invention, The control
`means of the magnetic disk drive which considers that two or more magnetic disk drives are one
`virtual magnetic disk drive which makes all the storage areas of the magnetic disk drive of these
`plurality the storage area, and controls them, It has magnetic-disk share equipment provided with a
`security management means to manage the available right of two or more personal computers of
`each, which can be set to the storage area of the virtual magnetic disk drive, Two or more personal
`computers access a virtual magnetic disk drive according to an available right, respectively.
`[0007]
`[Function]That thing [ accessing like ] which is a storage area of one magnetic disk drive for each
`personal computer about all the storage areas of two or more magnetic disk drives is made possible,
`The available right of two or more personal computers of each to receive the storage area of the
`one virtual magnetic disk drive is specified and managed for each microcomputer of every.
`[0008]
`[Working examp|e]Next, with reference to Drawings, it describes about the working example of the
`present invention.

`
`Page 2 of2
`
`[0009]Fig.1 is a block diagram showing the composition of one working example of the personal
`computer system containing the magnetic-disk shared device of the present invention.
`[0010]In
`the personal computer bodies 1 and 2 and
`are connected to the magnetic-disk
`shared device 3 via the interface boards 4 and 5 and
`The magnetic disk drives 8-12 are
`connected to the magnetic-disk shared device 3. The magnetic-disk shared device 3 comprises the
`magnetic disk control 6 and the partition control table 7.
`[0011]The access request from to the personal computers 1 and 2 and the magnetic disk drives
`8-12, It is notified to the magnetic disk control 6 through the interface boards 4 and 5 for magnetic
`disks, and
`and converts to the access request to the virtual magnetic disk drive over the
`magnetic disk drives 8-12 in the magnetic disk control 6. The above processing enables the
`magnetic disk drives 8-12 to treat all the storage areas of the magnetic disk drives 8-12 as one
`virtualized magnetic disk drive which is made into its record section from a personal computer body.
`
`[0012]A security management classifies the storage area of an above-mentioned virtual magnetic
`disk drive, It is for setting the available right for each personal computer of every to each classified
`portion (it is called a partition), and preventing unjust access, and is carried out by creating the
`partition control table 7. There are R (reading), W (writing), 0 (creation), D (elimination), and X
`(execution) in the right to access to a partition.
`[0O13]Fig.2 is an example of a partition control table. Reading, write creation, and execution are
`possible for the personal computer 1 to the partition 1, reading and writing are possible for it to the
`partition 2, and reading is possible for it to the partition 3. Reading, write creation, and execution are
`possible for the personal computer 2 to the partition 1, and reading is possible for it to the partition
`3. Reading, write creation, and execution are possible for the personal computer 3 to the partition 1,
`and reading is possible for it to the partition 2. it becomes possible to prevent unjust access which
`is not allowed the use from a personal computer by the above-mentioned security management
`means.
`
`[0014]
`[Effect of the lnvention]As described above, the personal computer system which has a magnetic-
`disk shared device of the present invention, By accessing all the storage areas of two or more
`magnetic disk drives from each personal computer as a storage area of one magnetic disk drive, and
`managing the access right of each personal computer, While making it possible to treat the data of
`the size exceeding the storage capacity of one magnetic disk drive, It makes it possible to share two
`or more magnetic disk drives with two or more microcomputers, and there is an effect which can be
`managed collectively without storing data with each personal computer.
