Abstract

High speed accessing is necessary for optical disk drives, which are used as computer peripheral equipments. A direct track seeking technique was introduced and a new light weight moving part was designed to make the track seeking time shorter. The average seeking time was reduced to 18 ms in an experimental optical disk drive, using an experimental 86 mm disk which was recorded in a sampled servo format.
