Latest Patents

Schaffner holds a patent for a "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 technology generates a unique binary sequence (UBS) code, which is stored in the indexing bits of the servo wedges. The bits are read from the servo wedges to provide unique identification of head position. This invention allows for the identification of each servo wedge and data field, even under different heads. It is designed for initial position detection, position verification during normal operation, and position verification upon head switching. The invention also incorporates a confidence block to assess the confidence level of head positioning, ensuring reliable operations such as reading and writing information on a disk.
