Abstract

PURPOSE:To read and write the contents of a floppy disk produced in another system by specifying a physical format via a read control part and controlling a read/write part via a write control part so as to perform a writing job in a prescribed format. CONSTITUTION:When a recording medium 1 is put into a recording medium read/write part 2, the part 2 informs a read control part 3 of the recording medium. The part 3 controls the part 2 to specify a physical format of the medium 1 and then retrieves all ID positions of the physical format in a proper format dictionary 5 to give an instruction to the part 2 to read all values of the retrieved ID positions. The part 2 reads the information recorded in the medium 1. A control program deciding part 4 compares the read information with the contents of the dictionary 5 and specifies a control program. Then the part 4 retrieves a logical format of the specified program out of the dictionary 5 and writes the data 7 into the medium 1 in the logical format.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a method for processing multiple types of recording media created in multiple operating system environments by using only a single operating system. Operating 2 handled...

The present invention relates to an information processing device that specifies a system and reads and writes files in a format specific to that operating system.

Conventional technology As a conventional information processing device, MS-DO8 (registered trademark)
The system will be explained using FIG.

As shown in FIG. 3, the floppy disk 51 is inserted into the floppy read/write section 52, and the read/write control section 53 issues instructions to the floppy read/write section 52 to read or write files existing on the floppy disk 51. In this case, in the case of the first disk access after the floppy disk 61 is inserted, the read/write control section 63 instructs the read/write section 52 to read a specific section in the floppy disk 51, and the media determination section At step 54, it is determined whether the floppy disk is a floppy disk for MSDO8. The media determination unit 54 determines that the inserted floppy disk is MS-D.
If it is determined that the disk can be handled by O3, the read/write control unit 63 performs normal data reading and writing to the Fronby disk. In addition, if the media determining unit 54 determines that the inserted floppy disk is a disk that cannot be handled by the MS-DO3, the floppy disk is not read or written to the floppy disk, and the floppy disk is A message indicating that the disc cannot be handled by MS-DO3 is displayed on the display section 56.

As shown above, MS-DO8 determines whether the floppy disk of its own system is 70 bits or less, and reads and writes to the floppy only if it is the floppy disk of its own system.

Problems to be Solved by the Invention However, with the above configuration, if a floppy disk from another system is inserted, only a message indicating that it is not the own system is displayed, so it is completely impossible to use the other system's floppy disk. The problem was that floppy disks could not be read or written.

In view of this, an object of the present invention is to provide an information processing device that allows a single system to read and write not only the contents of its own floppy disk but also the contents of floppy disks created in other systems.

Means for Solving the Problems In order to solve the above problems, the information processing device according to the present invention has the following steps:
a recording medium read/write unit that reads and writes information to and from the recording medium;
a read control i# unit that controls the recording medium read/write unit to read a specific portion of the recording medium; and a control program judgment that determines a control program for the recording medium based on information read by the read control unit. and a write control unit that controls an 11th edition recording medium read/write unit to write information to the recording medium based on the format of the control program determined by the control program determination unit.

Effects of the present invention [2] According to the technical means described in IJ, the reading control section controls the recording medium read/write section, specifies the operating system of the floppy disk, and writes in a format based on the format of the operating system. The control section controls the recording medium read/write section and writes data to the floppy disk.

Example Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a configuration diagram of an embodiment of an information processing apparatus according to the present invention. 1 is a recording medium, such as a floppy disk. Reference numeral 2 denotes a recording medium reading/writing section, which reads information in the recording medium 1 and writes information into the recording medium 1.

Reference numeral 3 denotes a reading control section, which controls the recording medium reading/writing section 2 and reads out information. Reference numeral 4 denotes a control program determining section, which searches the information read by the recording medium read/write section 2 according to instructions from the reading control section 3 using a unique format dictionary 5 and determines the control program for the recording medium 1. Reference numeral 6 denotes a write control unit, which controls the recording medium read/write unit 2 to write control programs 6/, determined by the control program determination unit 4.

Data 7 is written to the recording medium 1 in a format specific to the RAM.

The operation of the information processing apparatus of this embodiment configured as described above will be described in detail below.

When the recording medium 1 is inserted into the recording medium reading/writing section 2, the recording medium reading/writing section 2 notifies the reading control section 3 that the recording medium 1 has been inserted.

Having received the notification, the read/write control unit 3 controls the recording medium read/write unit 2 to identify the physical format of the recording medium 1, and further searches for all ID positions of the physical formant in the 5-width unique formant dictionary. An instruction is given to the recording medium reading/writing section 2 to read all the values of the searched ID positions. Based on the instruction, the recording medium reading/writing section 2 reads the recording medium 1.
Read the information recorded inside. The control program determination section 4 compares the read information with the contents of the unique format dictionary 6 to identify the control program.

In the unique format dictionary 5, the physical format information of the recording medium, the location where the ID is written, and the I
The value of D, the type of control program, and the type of logical ring format are stored in pairs.

For example, if the physical format is 2HD and 0x5F is written in the o-th sector position of the first trunk, the control program is oSl, and the logical format is LFM.
It is Tl. The write control unit 6 searches the unique format dictionary 6 for the logical format of the control program specified by the control program determination unit 4, and controls the recording medium read/write unit 2 to write the data 7 in that logical format. The recording medium read/write unit 2 writes data 7 to the recording medium 1 according to instructions from the write control unit 6.

In this embodiment, the case where the data 7 is written to the recording medium 1 has been explained, but the control program of the recording medium 1 is specified and its logical format is written to the unique format dictionary 5.
It is also possible to search for and read data stored in the recording medium 1.

As described in detail, the present invention allows a single operating system to handle floppy disks created with various operating systems. Instead, tasks that conventionally required reading and writing to a floppy disk can be performed immediately after restarting the system that supports the floppy disk. Furthermore, the user no longer has to be aware of which operating system each floppy disk is compatible with, which greatly improves operability. Therefore, the information processing device according to the present invention has extremely high industrial value.
