Abstract

PURPOSE: To ensure the retrial processing when write-in error is produced, by writing in the record block, after taking longer the IBG length than the standard length by an arbitrary value, when the byte number of write-in information is less than the set value.
CONSTITUTION: The write-in information to the magnetic tape is temporarily stored in the data buffer 7 in the set value N-byte via the interface circuit 6. In this case, when the number of write-in information is recognized at the detection circuit 9 as N-byte or more, after IBG is fetched by the standard number, the write-in information is written and write-in is continued until the write-in information from the upper rank unit is absent. If the number of bytes of write-in information is recognized as N-byte or less, after forming the IBG length sufficiently longer than the time for the standard IBG length, the write-in information of the data buffer 7 is all written on the magnetic tape to complete the write-in processing.
