ABSTRACT:
In a magnetic layer storage having a magnetic head positionable relative to a storage medium, a reference storage medium produced with high precision is employed for the individual calibration of the storage tape drive, and particularly a positioner means thereof. This reference storage medium carries a track pattern adapted to the respective application and whose exact position is known. During the test run of each and every individual tape drive, this reference storage medium is read, and the read signals are evaluated in order to identify offset of actual position of the magnetic head from its absolute position defined by the reference storage medium. Individual correction factors can be acquired from the relationship of the absolute position to the actual position, these correction factors being stored in the control electronics and being employed during normal operation for correcting the tolerances of the positioner means or of the magnetic head itself.
