Abstract
In order to realize high-speed access using a direct seeking system, new methods of tracking error signal transformation, relative velocity detection, and double window detection have been developed. These methods were applied to a 5.25” magnetooptical disk drive, and a direct seeking system whose counting error is less than one track was realized.
