Abstract
PURPOSE: To perform writing of the next track while following the final track by moving a light beam for a specified distance based on the tracking signal of the final track having been stored at the recording.
CONSTITUTION: The tracking signal of the final track having been stored in a memory 6 is converted to an analog signal in a D/A converter 18 and the DC signal to deflect the beam by as much as the intertrack spacing is added by an adder 7 and is applied to a driver 12 via switch 13 to drive a galvanomirror 3. At this same instant, in order to start recording the increase in the laser output via switch 19 and the singal inputting from an information soruce 5 are accomplished by the instruction of a sequence control circuit 21, then a modulator 22 is driven via driver 26, whereby the recording of the next track of the final track is accomplished. thereby, writing of the next track may be performed while following the final track.
