Claims (1)
転駆動系により回転されている記録媒体に対し光
ヘツドからの光を照射して記録媒体に記録されて
いる情報を読取る光ヘツドアセンブリとを有する
光読取り装置において、この光ヘツドアセンブリ
を固定配置するとともに、前記回転駆動系を、前
記光ヘツドが記録媒体の半径方向に相対的に移動
するように前記記録媒体とともに移動可能にし、
かつ、前記回転駆動系を移動させる駆動源を設け
たことを特徴とする光読取り装置。 An optical system that includes a rotational drive system that rotationally drives a recording medium, and an optical head assembly that irradiates light from an optical head onto the recording medium being rotated by the rotational drive system to read information recorded on the recording medium. In the reading device, the optical head assembly is fixedly arranged, and the rotary drive system is movable together with the recording medium so that the optical head moves relative to the recording medium in a radial direction;
An optical reading device further comprising a drive source for moving the rotational drive system.
