Latest Patents

One of his latest patents is titled "Disk file with multiplexed servo system." This invention involves a disk file that includes multiple disk surfaces, on which servo information is recorded with an offset in azimuth from one disk surface to another. Each head comprises a magnetoresistive stripe for reading and an inductive write coil. The servo system reads servo information from each disk in turn, multiplexing the signals from each disk together to form a single position error signal (PES). The separation of the servo multiplexer, attached to the MR stripes, from the write multiplexer, attached to the inductive coils, avoids problems due to contamination of the servo signal by the write signal. A least squares fit is used to generate the PES from the series of servo samples from each disk surface.

Another significant patent is "System and method for servowriting a magnetic disk drive." This invention provides a system and method for writing a servo pattern after the head disk assembly (HDA) is sealed. A clock track is written inside the sealed HDA using a Monte Carlo technique. The clock track is read by a magneto-optical head through a window in the HDA housing, and the time transitions therefrom are used to control the product heads. The entire servo pattern for the disk drive is thus written with the HDA unit completely sealed.
