Latest Patents

One of his latest patents is titled "Disk drive biasing timing recovery measurements for spiral tracks based on radial location of head." This invention involves a disk drive that includes a head actuated over a disk with multiple spiral tracks. Each spiral track contains a high-frequency signal interrupted by a sync mark. The read signal from the head is processed to detect sync marks during spiral track crossings. Timing recovery measurements are generated based on these detected sync marks and are biased according to the radial location of the head. A servo write clock is then produced in response to these biased measurements, which is used to write product servo sectors to the disk.

Another significant patent is "Disk drive centering sync frames on sync marks of a spiral track." This invention describes a disk drive where a head is actuated over a disk with spiral tracks. A first sync frame is opened in response to a frame offset during the disk's first revolution, corresponding to the head approaching a sync mark. A position error signal is generated to represent the difference between the target framing and the detected framing of the sync frame. The frame offset is adjusted based on this error signal, allowing for improved accuracy in subsequent revolutions.
