Abstract
A dual-scan master calibration tape is prepared and used for adjusting guide elements of a magnetic tape drive. The dual-scan master calibration tape is generated by transporting the master calibration tape past a rotating drum whereon a write head is mounted and activating the write head only during every other rotation of the drum. In use, the master calibration tape is transported past a read head in a manner whereby, for a track pre-recorded on the master calibration tape, the read head separately follows a first path over the track and a second path over the track. A first path read signal is generated as the read head follows the first path over the track; a second path read signal is generated as the read head follows the second path over the track. Both the first path read signal and the second path read signal are used to determine a calibration indicia for the tape drive.
