ABSTRACT:
Data reliability testing for a magnetic tape drive is conducted separately for the channels of a magnetic tape drive which write and read tracks of a multiple track magnetic tape. Memory stores testing data representing data separately written to tracks of a multiple track magnetic tape; each of a plurality of read channels reads data sensed by a tape head from a separate track of a magnetic tape; and error processing logic detects differences between data from each of a plurality of the read channels, and stored testing data of the memory representing data written to the same separate tracks.
