Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a recording device recording medium identification display system, in particular, a method for reading the contents of a recording medium installed in a recording device and identifying the volume number and/or file name recorded in the contents. This invention relates to a method for identifying and displaying recording media in a recording device, which is displayed on a visible display unit provided in the recording device to prevent mistakes when handling the recording media.

Traditionally, magnetic tape devices, magnetic disk pack devices,
Machine numbers were assigned to correspond to magnetic recording devices such as magnetic drum devices, and a system was adopted in which system configurations were managed based on the machine numbers.

However, in online systems such as banking systems, hundreds of magnetic recording devices are now used, and the magnetic recording media actually installed in each magnetic recording device can be identified by, for example, volume numbers or file names. It has come to be managed by.

That is, when a magnetic recording medium constituting one magnetic recording device is loaded, the central processing unit performs an automatic volume number identification function (
AVR function) can be used to automatically check which magnetic recording device is loaded with a volume number recorded on the magnetic recording medium by reading the volume number recorded on the magnetic recording medium, or to print it out on the console. People are starting to do things like that.

However, in the case of a huge system as described above, the number of operations performed by the operator to mount and remove the recording medium increases, and the operator must check the print contents printed by the console each time, which becomes extremely troublesome.

Furthermore, unexpected mistakes may occur if the console and magnetic recording device are installed far apart.

The present invention aims to solve the above points,
The purpose of this system is to provide a visual display unit corresponding to each magnetic recording device so that the volume number of the actually installed recording medium can be easily identified.

For this reason, the recording device recording medium identification display method of the present invention uses the central processing unit, main storage device, input/output control device, and stored data to identify the volume number of the device and/or the file name recorded in the device. In a data processing system equipped with a console device and a plurality of recording devices to which recording media for recording are loaded, when a recording medium is loaded in the recording device and/or a predetermined event occurs for one of the recording devices. It has a function of reading the volume number and/or the file name recorded on the recording medium and registering it in the recording medium management table when an instruction is given to make a file accessible;
Further, a visible display unit is provided corresponding to the plurality of recording devices, and the content of the recording medium management table is referred to and displayed on the display unit, and the central processing unit is configured to display the contents of the recording medium management table on each of the recording devices. The volume signal and/or the file name are read for each recording medium installed in the storage device, and the volume number and/or file name is displayed on a display unit provided in the corresponding recording device. It is characterized by

This will be explained below with reference to the drawings. The figure shows the configuration of an embodiment of the present invention.

In the figure, 1 is a central processing unit, 2 is a main storage device, 3 is a channel, 4 is a magnetic tape control device, 5-ro to 5-n are husband magnetic tape devices, 6 is a console, 7-0 to 7-
8-0 to 8-n are visual display devices (including printers, etc.), and 9-ro to 9-n are registers that are connected to the display devices. The data to be displayed (volume number and file name) is stored, 10 is a recording medium management table provided on the main storage device 2 and has an area corresponding to each magnetic tape device, and 11 is a microprocessor. 12 is a demodulation circuit that demodulates information read out from one selected magnetic tape device; 13 is a modulation circuit that controls the entire magnetic tape control device 4; 14 is a data buffer, and 15 is a lead-in control circuit unit which performs processing for sending the read data to the central processing unit 1 side. 16 is a read-out control circuit section which controls the process of writing the write data from the central processing unit 1 side, 17 is a selection circuit, and 18 is a printer.

Write data sent from the central processing unit 1 to the magnetic tape device is sent to the data buffer 14 via the selection circuit 17 under the control of the read-out control circuit 16.
The signal is supplied to the magnetic tape device, modulated by the modulation circuit 13, and sent to the magnetic tape device.

Also, read data from the magnetic tape device 5 is
Under the control of the input control circuit 15, the signal is supplied to the data buffer 14 via the selection circuit 17, and sent from the data buffer 14 to the channel side.

Although not shown, a volume number is written on the magnetic tape 7 in the form of recorded information in order to indicate which volume information is written or stored on the magnetic tape.

Also, one or more file names belonging to one volume number are similarly written in the form of recording information.

As mentioned at the beginning of this specification, recently a method has been adopted for managing the magnetic tape itself actually installed in a magnetic tape device, for example, a magnetic tape 7-0 is installed in a magnetic tape device 5-0. Then, the central processing unit automatically reads the volume number recorded on the magnetic tape 7-0 by the AVR function.

That is, it controls the magnetic tape control device 4, stores the volume number in the recording medium management file 10 on the main storage device 2, and manages what kind of magnetic tape is actually installed in which magnetic tape device. be made to do.

And a magnetic tape with a volume number consisting of, for example, 7
-0, magnetic tape device 5-0
be accessed.

Furthermore, information about which magnetic tape device and which volume number the magnetic tape is actually loaded is printed out on the console 6.

However, as stated at the beginning of this specification, when the number of installed magnetic tape devices increases, and the distance between the installation position and the installation position of the console 6 becomes too large, it becomes troublesome for the operator to operate the magnetic tape. This will also lead to unexpected mistakes.

For this reason, in the case of the present invention, as shown in the figure, for example, visible display devices 8-0 to 8-n are provided corresponding to the magnetic tape devices 5-0 to 5-n, respectively, so that each magnetic tape device can be actually displayed. To directly display the volume number ○○○ of the installed magnetic tape.

That is, by directly utilizing the fact that the central processing unit 1 has the AVR function as described above, the recording medium management table 1
The contents of 0 are displayed on the visual display device 8 via the magnetic tape control device 4.

For this display, the central processing unit 1 gives an instruction to the microprocessor 11 on the magnetic tape control device 4, and the microprocessor 11 receives the contents of the management table 10 and registers 9 to 9 shown in the figure. -n and displayed on the display devices 8-b to 8-n.

Further, the central processing unit is configured to give an instruction to the magnetic tape control device to specify a file name and enable access to the file.

In this case, for example, a read instruction is given to the magnetic tape device 5-0, and the read data that is also read from the magnetic tape 7-0 is supplied to the data buffer 14.

At this time, the lead-in control circuit section 15 decodes the read data on the data buffer 14, and when it detects a file name that matches the file name instructed from the central processing unit 1 side, it notifies the microprocessor of this fact. Notify 11.

As a result, the microprocessor 11 stops the read process for the magnetic tape device 5-0, and notifies the central processing unit 1 that the coincidence has occurred.

A process called normal file opening as described above is performed, and at this time, for example, the magnetic tape device 5-0
Information about which files the magnetic tape 7-0 mounted on the magnetic tape 7-0 is accessible to is stored in the recording medium management table 10 described above.

Then, print/print on console 6 according to Issui.
be outed.

In the case of the present invention, this fact is directly utilized to cause the central processing unit 1 to display the file name on the display device 8-0.

In this case, it may be considered that the microprocessor 11 receives the contents of the management table 10, sets the file name in the register 9-0, and displays the file name.

Of course, when an instruction is given to make another file on the magnetic tape 7-0 accessible, the microprocessor 11 automatically erases the file name on the register 9-0 and erases the file name display. .

When a new file becomes accessible, the new file name is displayed as described above.

Furthermore, a magnetic tape device such as 5-0 to magnetic tape 7-0
If the above-mentioned recording medium management chief 10 is removed,
The above information is erased, and the entire display on the display device 8-0 is erased accordingly.

As explained above, according to the present invention, a visible display device 8 is provided for each recording device, and it is possible to check what volume number the recording medium is actually loaded in, and what file name the file has. Directly display whether it is accessible.

Therefore, the operator does not have to choose the installation position of the console 6 one by one, and mistakes in handling the recording medium are largely prevented.

For this reason, it is extremely effective in improving reliability in automatic driving systems that need to manage the volume of a large amount of recording media, such as in a calculation center.

Further, in the case of the present invention, the existing AVR function is used as is, and it is sufficient to simply provide a visual display device corresponding to each recording device and add a microprogram routine for the microprocessor 11.
