摘要：In a magnetic layer storage having a magnetic head positionable relative to astorage medium, a reference storage medium produced with high precision is employedfor the individual calibration of the storage tape drive, and particularly a positionermeans thereof. This reference storage medium carries a track pattern adapted to therespective application and whose exact position is known. During the test run of each andevery individual tape drive, this reference storage medium is read, and the read signalsare evaluated in order to identify offset of actual position of the magnetic head from itsabsolute position defined by the reference storage medium. Individual correction factorscan be acquired from the relationship of the absolute position to the actual position,these correction factors being stored in the control electronics and being employedduring normal operation for correcting the tolerances of the positioner means or of themagnetic head itself.
