Abstract
A data recorder having a self-diagnostic function using a magnetic tape accommodated in a case (or cassette). The case is provided with holes indicating a grade of the magnetic tape. When the magnetic tape unit is loaded (mounted) in the data recorder, the holes are detected and identified. When the identified grade is that for the self-diagnosis, the self-diagnosis is executed using that magnetic tape. Cleaning of a head is also carried out using the identified cleaning magnetic tape.
