Latest Patents

One of Quoc Dang's latest patents is titled "Disk drive employing stream detection engine to enhance cache management policy." This invention discloses a disk drive that includes a disk, a head actuated over the disk, and a host interface for receiving disk access commands. The innovative stream detection engine evaluates these commands to detect multiple streams accessed by the host, maintaining a data structure for each stream to track the frequency of disk access commands. This allows the disk controller to select the most relevant stream for servicing based on the frequency counters.

Another notable patent is "Disk drive implementing wear prevention in a high frequency access band of tracks." This invention describes a disk drive that identifies a band of tracks associated with an access command and maintains a counter to track the time the head spends within this band. The control circuitry moves the head out of the band to prevent wear, thereby enhancing the longevity of the disk drive.
