Abstract

PURPOSE: To detect the malfunction by securing an automatic adding and reading the sequence number to the data on the magnetic tape via the magnetic tape control unit and then examining whether the sequence of the blocks is correct or not when the data is read in through the magnetic tape.
CONSTITUTION: The tape read-in request is transmitted to the magnetic tape control unit 4 from the central processor 1 via the channel device 3. And a decision is given whether the information I showing that the sequence information S1, S2, S3... are included is printed immediately after the load point B of the magnetic tape. The unit 4 reads in the data D1t, D2t, D3t... through the magnetic tape and by the read-in command and then gives a comparison between the information S1, S2, S3... which are added to the data D1, D2, D3... and the sequence information SC in the control unit. And in case a coincidence is obtained, the sequence information is excluded to send only the data to the main memory 2.
