Latest Patents

One of his latest patents is titled "Method and apparatus for providing positional information on a disk." This invention outlines a method for positioning a read/write head in a hard disk drive. The method involves providing a disk with multiple tracks, each containing a servo field with servo bits. These bits are read to generate a position signal for the read/write head. The invention determines the difference in position between an initial and a subsequent position of the read/write head on a track, with the subsequent position occurring after the head has moved one revolution. The initial and subsequent positions are laterally offset, and a compensation signal is generated based on these positions. The position signal and compensation signal are then combined to create a compensated position signal for accurate positioning of the read/write head.
