Method and apparatus for determining track density during a servo-track writing operation |
摘要 |
Disk drives are produced having a track density that is determined during a servo-track writing operation. A plurality of calibration tracks is written onto a storage medium of a disk of a head-disk assembly at a calibration track density. The calibration track density corresponds to a portion of a nominal track density profile. An aspect of the servo performance of the head-disk assembly is measured at the calibration tracks. A selected track density profile is identified based on the measured servo performance. The plurality of tracks is written to storage medium at the selected track density profile.
