Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cartridge type magnetic tape device, and more particularly to display of processing status of a magnetic tape.

[Prior Art] Conventionally, this type of cartridge-type magnetic tape device has been used to process various information by storing various information on a cartridge-type 5m tape and reading the information from the magnetic tape as necessary. I'm here.

In particular, since it is a cartridge type, it is easy to handle.

[Problems to be Solved] The above-mentioned cartridge type magnetic tape device has trouble information such as the number of errors that occur during magnetic tape processing, information processing amount, and maintenance information that includes information such as fault management data sent from a host device. Therefore, the operator cannot easily obtain maintenance information.
There are problems in that it takes time to handle and process magnetic tapes, and important information can be lost due to mounting of defective magnetic tapes.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a cartridge magnetic tape device that can display maintenance information and facilitate processing, handling, and management of magnetic tape.

[Means for Solving the Problem] In order to achieve the above object, the present invention provides a magnetic tape device that uses a cartridge-type magnetic tape as an information recording medium, and solves a problem that occurs during the processing of the magnetic tape.
A storage unit that stores maintenance information including processing amount information and information sent from the host device, a detector that detects the physical start end of the magnetic tape, and a detector that stores the physical start end and logical start end of the magnetic tape after processing of the magnetic tape is completed. a writing/reading unit for writing information in the storage unit between the starting end and reading information that has already been written between the physical starting end and the logical starting end; and a magnetic tape device for displaying the maintenance information. and a display section provided on the outer surface of the display.

[Operation] According to the above configuration, the maintenance information is written between the physical start end and the logical start end of the magnetic tape, and when the magnetic tape is used, the stored maintenance information is read out. The information will be displayed on the display section in the form of characters, etc. Therefore, the state of the magnetic tape can be easily grasped by this display.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a configuration block of a cartridge-type magnetic tape device according to an embodiment, and the magnetic tape device l controls a control section 2 that controls the entire device, and detects the physical start end of a magnetic tape 7. A storage unit 4 that stores maintenance information such as the number of errors that occur during magnetic cheese processing, the amount of information processed, and failure management data sent from a host device.
Equipped with In addition, the maintenance information stored in the storage section 4 is written to the magnetic tape 7, and the maintenance information read by the writing/reading section 5 is read out from the magnetic tape. , a display section 6 for displaying symbols and the like.

The embodiment has the above configuration, and next, reading, displaying, and writing of maintenance information from the magnetic tape will be explained.

First, when the magnetic tape 7 is mounted, the control section 2 instructs the detector 3 to detect the physical start end of the magnetic tape 7 via the control signal line 12. After receiving the instruction, the detector 3 performs an operation to detect the physical starting edge of the magnetic tape 7, and then the controller 2
The completion of detection is notified via the control signal line 12. Then, the controller aS2 sends a command to the write/read unit 5 via the control signal line 14 to change the maintenance information stored on the magnetic tape 7! +! L or 6 eggplants L or η Eap Kikai or 6
L-) The write/continue output unit 5 reads maintenance information via the data line 26, and this maintenance information is output to the display unit 6 via the data line 25, and the failure data is displayed on the display unit 6. , fault management data, etc. are in text.

Displayed with symbols etc.

On the other hand, failure information such as the number of read or write errors that occur during processing of the magnetic tape 7 is detected by the control section 2 and stored in the storage section 4 via the data line 23. Further, maintenance information sent from the host device is received by the control unit 2 via the data line 21, and is further received by the storage unit 4 via the data line 23.
is memorized.

Then, when writing maintenance information, the control unit 2
The detector 3 receives the instruction via the control signal line 12 to detect the physical starting end of the magnetic tape 7.
performs the operation of detecting the physical start end of the magnetic tape 7, and the control signal line 12 causes the detection 2 to perform the write/write operation via the control signal 14.
The reading unit 5 is instructed to write the maintenance information stored in the storage unit 4 onto the magnetic tape 7, and the writing/reading unit 5 receiving this instruction writes the maintenance information stored in the storage unit 4 via the data line 24. The maintenance information is read and written between the physical start end and the logical start end of the magnetic tape 7 via the data line 26. At the same time, the maintenance information is also sent to the display section 6 via the data line 25. The display content on the display unit 6 will be updated, so that the operator can receive the latest information.

[Effects of the Invention] As explained above, according to the present invention, the magnetic tape has
Since the maintenance information necessary for the operator is written in, and this maintenance information is read out and displayed while the magnetic tape is being processed, processing and handling of the magnetic tape becomes easier.
In addition, defective magnetic tapes are eliminated and magnetic tape management becomes easier.

Furthermore, it is possible to prevent writing failures and omissions of recorded data caused by defective magnetic tapes, thereby improving the reliability of the system.
