Latest Patents

One of Martin R. Green's latest patents is focused on disk drive servo control. In this innovation, a reference track is written in the outer guardband of the servo surface and each of the data surfaces. Supplemental position error signal (PES) values are obtained from the difference of servo and data surface samples at various locations around the disk. These values are stored for access during read/write operations. The supplemental PES values are combined with dedicated surface PES values to yield a composite PES that accurately follows the data track centerline of the disk surface being addressed. Additionally, the supplemental PES values are periodically updated to enhance accuracy.

Another significant patent involves a transducer head skew arrangement for a disk drive system. This arrangement is utilized in a multiple disk drive data storage system, which includes several magnetic disk surfaces that rotate simultaneously. A sequence of servo information tracks is arrayed on a dedicated servo disk surface, and servo reference tracks are written on each data disk surface. This innovative design minimizes track-to-track seek time and increases overall data transfer rates for accessing multiple data cylinders.
