ABSTRACT:
In a magnetic disc device, track bytes are added to a record which is to be stored in a cylinder of a magnetic disc in order to utilize additional magnetic disc devices of a different type in the same manner as the first-mentioned magnetic disc device. The magnetic disc device provides track byte check device which checks track bytes read from the record for errors, stores the track bytes in a track byte register when they are correct, and, if the stored track bytes are re-read, utilizes the correct contents stored in the track byte register as the track bytes of the record.
