Abstract
PURPOSE:To improve recording position accuracy with a simple constitution by generating a recording signal to synchronize with a pulse signal synchronizing with the rotation of a disk-shaped recording medium at a recording control signal forming part and controlling a light beam irradiation. CONSTITUTION:A pulse Sd' synchronized with the rotation of a disk 20' by a motor encoder 26 of a motor 22 to turn the disk 20' through a turn table 24, a PLL 38, etc., is outputted and supplied to a recording control signal forming part 36. The forming part 36 generates recording signals S1' and S2' synchronized with a pulse Sd', an optical beam modulator 34, an optical beam deflecting system, etc., to form an irradiation laser beam for recording are controlled and the optical beam irradiation to the disk 20' is controlled. By the simple constitution, the recording position is controlled and the information recording position accuracy is increased in accordance with the rotation fluctuation of a disk.
