Latest Patents

Among his latest patents is a disk drive implementing wear prevention in a high-frequency access band of tracks. This invention involves a disk with multiple tracks, a head actuated over the disk, and control circuitry that services access commands from a host. The control circuitry identifies a band of tracks related to the access command and maintains a counter to track the time the head spends within that band. It then moves the head out of the band to prevent wear. Another significant patent is for a disk drive employing off-line sector verification and relocation of marginal sectors discovered during a read error recovery procedure. This innovation ensures that if multiple retries are needed to recover a data sector, it is added to a marginal sector list. During an off-line scan, these sectors are verified, and if verification fails, the sector is relocated.
