Abstract
PURPOSE: To make it possible to exactly carry out recording without being affected by a tracking distortion, by using a recording device which is interlocked with a tracking device by retaining relation of a fixed position.
CONSTITUTION: A light flux 7 from the light source 6 is converged and radiated on the recording medium 1 through a light modulator 8, a light flux divider 9, reflectors 11 and 12, a splitter 13, and a rotary mirror 16 and a lens 18 to which rotary vibration is given by a tracking mirror driving element 15 in the optical transfer mount 14. A reflected ray from the medium 1 is projected into the detective unit 20 through the splitter 13, and a tracking control signal and an information regeneration signal are obtained from the detecting output. And the information can be recorded as a track 301 in the position next to the track 203 with the same recording pitch and the same distortion shape, by making the unit a recording state under the condition that the divided light flux 7a performs tracking with fidelity to the distortion shape of the recording track 203, and by carrying out a light modulation 8.
