`(54) Title: PERSON/\I. COMPUTER SYSTEM
`(57) Abstract
`Objective
`To offer a personal computer system that
`allows sharing of multiple magnetic disk devices by
`multiple personal computers.
`
`Structure
`
`It has a magnetic disk sharing device 3
`equipped with a magnetic disk controlling
`mechanism 6 that controls multiple magnetic disk
`devices 8-12 by considering them as ! virtual
`magnetic disk device with all of their memory
`regions as a memory region, and a partition control
`table 7 that manages and specifies the access right
`of the respective personal computers 1, 2, -- -for
`each partition in the memory region of the virtual
`magnetic disk device. a11d each computer accesses
`the virtual magnetic disk device according to its
`respective access right.
`
`

`
`Claim
`
`1. A personal computer system, which is a personal computer system that includes
`
`multiple personal computers and multiple magnetic disk devices, characterized in that
`
`it has a magnetic disk sharing device equipped with a magnetic disk device controlling
`
`means that controls the aforementioned multiple magnetic disk devices by considering them as 1
`
`virtual magnetic disk device with all ofthe memory regions of said multiple magnetic disk
`
`devices as its memory region, and a security management means that manages the access right of
`
`the respective aforementioned multiple personal computers in the memory region in said virtual
`
`magnetic disk device,
`
`and the aforementioned multiple personal computers access the aforementioned virtual
`
`magnetic disk device according to the aforementioned respective access right.
`
`Detailed explanation of the invention
`
`[UOUI]
`
`Industrial application field
`
`This invention pertains to a personal computer system that includes multiple personal
`
`computers and multiple magnetic disk devices.
`
`[0002]
`
`Prior art
`
`A magnetic disk controlling device in a conventional personal computer system can place
`
`in correspondence only 1 physical magnetic disk device with l logical magnetic disk device, and
`
`this is also true with regard to magnetic disk management of the host software (operation
`
`system).
`
`[0003]
`
`Magnetic disk devices also carmot be shared by multiple personal computers.
`
`[0004]
`
`Problems to be solved by the invention
`
`The conventional magnetic disk controlling device described above has a specification
`
`where only 1 physical magnetic disk device can be placed in correspondence with 1 logical
`
`magnetic disk device, and there is a disadvantage that an amount of data that exceeds the
`
`capacity of l magnetic disk cannot be handled. There also is a disadvantage that a magnetic disk
`
`device cannot be shared by multiple personal computers.

`
`[0005]
`
`The objective of this invention is to offer a microcomputer system that has a magnetic
`
`disk controlling device that allows sharing of multiple magnetic disk devices by multiple
`
`microcomputers by handling data of a size that exceeds the capacity of one magnetic disk device
`
`by accessing all the memory regions of multiple magnetic disk devices as if the multiple memory
`
`regions were the memory region in I magnetic disk device from individual personal computers
`
`and managing the access right of individual personal computers.
`
`[0006]
`
`Means to solve the problems
`
`The personal computer system in this invention has a magnetic disk sharing device
`
`equipped with a magnetic disk device controlling means that controls multiple magnetic disk
`
`devices by considering them as I virtual magnetic disk device with all of the memory regions of
`
`these multiple magnetic disk devices as its memory region, and a security management means
`
`that manages the access right of the respective multiple personal computers in the memory
`
`region in that virtual magnetic disk device, and multiple personal computers access the virtual
`
`magnetic disk device according to the respective access right.
`
`[0007]
`
`Operation
`
`This allows individual personal computers to access all of the memory regions of
`
`multiple magnetic disk devices as ifthe memory regions were a memory region of l magnetic
`
`disk device, and the respective access right of the multiple personal computers for that memory
`
`region in 1 virtual magnetic disk device is specified and managed for each microcomputer.
`
`[0008]
`
`Application examples
`
`Next, an application exarnpie of this invention will be explained while referring to
`
`figures.
`
`[0009]
`
`Figure l is a block diagram that shows the structure of an application example of a
`
`personal computer system that includes the magnetic disk sharing device in this invention.

`
`

`
`[0010]
`
`In Figure 1, personal computers main bodies 1, 2, ---are connected to a magnetic disk
`
`sharing device 3 through interface boards 4, 5, ---. The magnetic disk sharing device 3 is also
`
`connected to magnetic disk devices 8-12, The magnetic disk sharing device 3 comprises a
`
`magnetic disk controlling mechanism 6 and a partition control table 7.
`
`[001 1]
`
`An access request from the personal computers 1, 2, ---to the magnetic disk devices 8-12
`
`is notified to the magnetic disk controlling mechanism 6 through the magnetic disk interface
`
`boards 4, 5,
`
`and it is converted to an access request to a virtual magnetic disk device that
`
`extends over the magnetic disk devices 8-12 in the magnetic disk controlling mechanism 6.
`
`Through the process above, the magnetic disk devices 8-12 can be handled from the personal
`
`computer main body as 1 virtual magnetic disk device with all of the memory regions of the
`
`magnetic disk devices 8-12 as its own |memory] region.
`
`[00 12]
`
`The security management divides the memory region of the virtual magnetic disk device
`
`described above, sets up the access right for each personal computer in each divided part (will be
`
`referred to as partition), and prevents illegal access. This is implemented by preparing a partition
`
`control table 7’. The access right to a partition includes R (read), W (write), C (create), D (delete),
`
`and X (execute).
`
`| 00 13 I
`
`Figure 2 shows an example of a partition control table. A personal computer I can read,
`
`write, create, and execute with a partition 1, can read and write with a partition 2, and can read
`
`with a partition 3. A personal computer 2 can read, write, create, and execute with partition 1,
`
`and can read with partition 3. A personal computer 3 can read, write, create, and execute with
`
`partition 1, and can read with partition 2. The aforementioned security management means can
`
`prevent illegal access for utilization from a personal computer that is not authorized.
`
`[0014]
`Effect of the invention
`
`As explained above, the personal computer system with the magnetic disk sharing device
`
`in this invention has the effect of handling data in a size that exceeds the memory capacity of l
`
`magnetic disk device by accessing all memory regions of multiple magnetic disk devices as ifthe
`
`multiple memory regions were the memory region of l magnetic disk device from individual

`
`personal computers and managing the access right of each personal computer and sharing
`
`multiple magnetic disk devices by multiple microcomputers for managing data in an aggregate
`
`instead of storing them in individual personal computers.
