Latest Patents

One of his latest patents is titled "Preventing damage to the heads and media in a removable cartridge and disk drive." This invention utilizes the integration of instantaneous velocities of the heads to estimate the distance they travel while latched. The disk drive can determine if the heads are properly parked based solely on the distance traveled, thus avoiding the use of costly sensors. In cases where the heads cannot be properly parked due to malfunctions, the disk drive stores a special code in nonvolatile memory. This code instructs the controller not to spin up or attempt to load the heads on any disk, preventing potential damage.

Another significant patent is the "Method and apparatus for providing extended functionality for a bus." This invention describes an information storage device that includes a cartridge removably inserted into a cradle with a drive module. The drive electronics circuit in the drive module is coupled to a hard disk drive mechanism in the cartridge. It operates through a bus switch and a bus to a bridge circuit in the interface module. The auxiliary circuit in the drive module is controlled by the bridge circuit and handles considerations related to the removability of the cartridge.
