Paper Abstract

High speed accessing using a split optical head with a linear actuator is presented. A new optical head, which can detect and compensate for the displacement between the optical axis and the optical head moving part, was developed for the linear actuator. The moving part weight for this disk drive is less than 30g. The 21 msec average coarse seeking time can be realized.
