Method for adaptively allocating data storage tracks in a disk drive to improve seek performance

摘要

A band of data storage tracks adjacent to an initial OD (outer diameter) limit are analyzed to determine a track defect density based on flagged tracks within the band. If the defect density exceeds a predetermined threshold, them the disk drive is reconfigured by adjusting initial OD and ID (inner diameter) limits to exclude the analyzed band and to maintain a targeted storage capacity. Adjusting the initial OD and ID limits improves the disk drive's seek performance which would otherwise be disproportionately impacted by the defect density in the analyzed band.
