Filed: 1985-07-15
Abstract: PURPOSE:To realize the small recording pit and to execute the higher density recording while it is prevented that the recorded point on the disk comes to be an ellipse by matching the spot of the laser light to the line speed of the disk, synchronizing and shifting it. CONSTITUTION:A laser beam 12 to pass through a lens 11 is irradiated to the disk not shown in the figure, and a spot 13 of the laser beam 12 can be made at the recording position on the disk. At such a time, when the disk is shifted in the (A) direction of an arrow at a high speed, the laser beam 12 is polarized in the (A) direction at a high speed, and thereby, the spot 13 is matched with the line speed of the disk, synchronized and shifted. For such a reason, the spot 13 is followed up while it is coincident with the recording position of the disk. Namely, the relative speed of the spot 13 of the laser beam 12 and the recording position of the disk comes to be zero. Consequently, a recording pit 14 will not extend long and come to be a circle.
