Abstract

PURPOSE:To prevent processing data from being lost suddenly by displaying the number of errors generated from a logical start to the completion of the processing of a cartridge type magnetic tape medium with a counter on the medium in performing the processing of the medium. CONSTITUTION:A control part 10 issues an instruction to reset a counter in the medium 11 to a display part 12 via a control signal 22 when detecting first the logical start of the medium 11 from the setting of the medium 11. Also, the control part 10 issues the instruction to count up the counter by one in the medium 11 to the display part 12 via the control signal 22 at every detection of the error being generated in an operation by indication from a host device. In such a way, when a series of processings of the medium 11 by a control signal 20 is completed, the number of errors generated in processing the medium 11 is left as being displayed on the counter in the medium 11, thereby, the number of errors can be read easily when an operator takes out the tape medium 11 from a magnetic tape device 1, and to prevent the processing data from being lost suddenly.

Referring to FIG. 1, a cartridge type magnetic tape device 1
(hereinafter abbreviated as the present device 1) is composed of a control section IO, a cartridge type magnetic chip processor with a counter, and a display section 12. The control unit IO accepts control information sent from the host device via the control signal 20, decodes the control information, and transmits the data line 30.3 and the control signal 21 as necessary.
The read/write of data from/to the cartridge-type magnetic tape 11 with a counter is controlled via the counter. Further, when the control unit IO first detects the logical start end of the cartridge-type magnetic tape 11 with a counter (hereinafter abbreviated as medium 11) from the set of the same medium 11, the control unit IO sends a control signal 22 to the display unit 12 to notify the Instructs to reset the counter in medium II.
