Latest Patents
One of his notable patents is titled "Method and apparatus for high fly write detection using stored amplitude values." This invention provides a method for detecting high flying conditions of a transducer head in a computer disk drive. The system allows for the detection of high fly write events that occur over one or a small number of data sectors. It offers high sensitivity and quick response by monitoring the strength of a signal derived from data written to the disk. If the monitored signal strength falls below a predetermined threshold, a high fly write event is signaled.
Another significant patent is "Method and apparatus for high fly write detection in a disk drive." This invention utilizes amplitudes of automatic gain control (AGC) fields to determine whether a high fly write condition exists. The process involves calibrating average amplitudes of AGC fields on a zone-by-zone basis for a head associated with a disk surface. During write operations, the head measures the amplitude of the AGC field and compares it to the average amplitude for the zone. If the difference exceeds a certain tolerance, it indicates a potential high fly write condition, prompting remedial actions.
