Abstract

PURPOSE: To ensure an easy and accurate recording of a spiral track form, by arranging the beams into the circumference direction of the track and then carrying out a tracking detection with the subsequent traking beams.
CONSTITUTION: For start of the recording, the magnetic disk 11 is distributed first, and then the tracking beams 54a and 54b are irradiated on the reference track 13. And a control is given while looking at the output of the differential circuit 30 and so that the reflected outputs may be equal between the beams 54a and 54b. After this, the motor 15 is turned to start the sending of the optical device into the direction of radius. Thus the recording is started from the end point of the track 13 and via the recording beam 52. As a result, the information signals of the track 53 are recorded into a spiral form.
