Latest Patents

One of his latest patents is titled "Method and apparatus for high fly write detection in a disk drive." This invention discloses a method for detecting a high fly write condition in a disk drive by utilizing amplitudes of automatic gain control (AGC) fields. The amplitude of an AGC field read by a head is generally related to the flying height of the head. The invention includes a calibration process to obtain average amplitudes of AGC fields on a zone-by-zone basis for a head associated with a disk surface. These average amplitudes are stored on the disk surface for later use. When a write operation is performed, the head measures the amplitude of the AGC field associated with a data sector. If the difference between the measured amplitude and the average amplitude exceeds a certain tolerance, a high fly write condition may exist, prompting remedial action.

Another significant patent is the "High fly write detection method," which provides a method and apparatus for detecting high fly write events in a computer disk drive. This invention allows for the detection of high fly write events occurring over very short time spans and offers high sensitivity. The method monitors the strength of a signal derived from a servo sector position burst and signals a high fly write event if the monitored signal strength is below a predetermined threshold.
