Abstract
A Dove prism is provided in a multiple beam optical disc record and playback system. In a multi-track optical system, the multiple spots formed in a multi-channel modulator are imaged on the record medium. The track-to-track spacing between adjacent tracks may be adjusted by rotating the Dove prism such that the angle formed between a line which passes through the center of the spots and the velocity vector of the disc is varied.
