Paper Abstract

A dual beam recorder for high density format has been developed. The recorder features remote control of size and mutual distance of both recording spots, a special beam pointing control system, and a high accuracy, laser interferometer controlled, radial drive. The recorder can switch between very dissimilar formats without intermediate alignment. The performance of the recorder has been shown for DVD, MO, and even higher density formats. Track pitches down to 0.7 micrometers have been realized.
