Paper Abstract

This paper describes a high speed and precise tracking servo system for an optical disk drive. For efficient production of television programs, an optical video disk recording system with high data transfer rate and large capacity is being developed. To realize a high data transfer rate, a high disk rotation speed is needed. Together with the utilization of short-wavelength lasers and an objective lens with a high numerical aperture, the track pitch on the disk must be reduced to enlarge the recording capacity.
