Abstract

PURPOSE: To make high-density recording possible easily and securely without any influence of eccentricity, etc., by storing the motion of a recording method in a scan on a reference track and then by controlling the motion of the recording method in recording on the next track.
CONSTITUTION: A recording-finished track on recording medium 1 is tracked while the turning of reflecting mirror 7, etc., is feedback-controlled via read beam from light source 4, thereby reading record. The detection signal of photodetector 18 for the reflected light of a light beam from light source 15 corresponding to the turning state of this reflecting mirror 7 is stored in memory part 20 which operates synchronously in a single turning period of electric motor 2 for driving medium 1. In recording after optical table 22 is moved by one pitch, the turning of reflecting mirror 7 is controlled on the basis of the memory contents of memory part 20, and consequently even in case of eccentricity, etc., information is recorded on the next track easily and securely without overlapping with the recording-finished track, increasing the recording density.
