Paper Abstract

Electro-optic (EO) scanners can be used as fine tracking actuators to improve the servo bandwidth in future high density/high data-rate optical disk drives. In this paper we report on the use of an EO scanner in a new optical tracking system. Track following has been accomplished with a servo bandwidth of 200 kHz and we have demonstrated track switching between nine tracks using only an EO scanner. A fine tracking experiment using an EO scanner has been demonstrated in parallel with a voice-coil actuated lens to expand the fine tracking range. Significant improvement in track switching speed and track following are demonstrated with the scanner/lens actuators as compared to tracking with the lens actuator alone.
