Abstract
PURPOSE: To record a track on a recording part well with maintaining an accurate track interval in a low mechanical accuracy by subjecting the reference track, which is recorded on a reference pattern material arranged adjacently to the recording material, to tracking and scanning the surface of the track accurately.
CONSTITUTION: Reference pattern material 31 where reference tracks 32-1, 32-2... having a prescribed accurate interval are recorded previously is arranged adjacently to recording material 1 and is fixed at a recording time. At a write time, the beam from laser light source 8 is not modulated by modulator 9 and is irradiated to recording plate 1 to detect first track 32-1, and this track is subjected to tracking to read and store the recorded number. Further, scanning is performed while subjecting track 32-1 to tracking accurately up to the end of the track, and recording track 35-1 is formed as the extension of this locus on recording plate 1. At this time, the beam is modulated by modulator 9 to record information. Next, reference pattern 31 performs read and scanning by switching object leanses 3 to 6 to read correct track 32-2, and similarly, track 35-2 is recorded.
