Latest Patents

One of her latest patents is titled "Position detection scheme for headerless disk controller." This invention provides a method and apparatus for position detection using a unique binary sequence encoded in indexing bits stored in servo wedges. The invention generates a unique binary sequence (UBS) code and stores the bits in the indexing bits of the servo wedges. These bits are read from the servo wedges to provide unique identification of head position. This technology allows for the identification of each servo wedge and data field, even under different heads. It can be utilized for initial position detection, position verification during normal operation, and position verification upon head switching. The invention also incorporates a confidence block to determine the confidence level of head positioning, ensuring reliable operations such as reading and writing information on a disk.

Another notable patent is for a "Disk drive with embedded finite field processor for error correction." This disk drive features error detection and correction capabilities, including a dedicated finite field processor that performs corrections and generates software syndromes for miscorrection detection. The processor operates over a finite field under program control, executing parallel finite field multiplication and addition operations in a single cycle.
