Rotating media storage device having a calibration track with unique calibration servo synch marks

摘要

Disclosed is a rotating media storage device (RMSD) that has at least one calibration track with unique calibration servo synch marks (SSM_cs). The RMSD includes a disk that comprises a plurality of tracks including a calibration track having a plurality of normal servo wedges distributed around the calibration track. At least one of the normal servo wedges includes a normal servo synch mark (SSM_N). Further, at least one calibration servo wedge is distributed between a pair of normal servo wedges. The calibration servo wedge includes a calibration servo synch mark (SSM_C). The calibration SSM_C includes a pattern that is different than the pattern associated with the normal SSM_N.
