ABSTRACT:
A media ID recording apparatus has an optical pickup20for forming an elongated optical spot on a recording surface of an optical disk DK; and a support table32for fixedly supporting the optical pickup20. The optical pickup20is fixed to the support table32via a wedge-like spacer33as tilted toward the radial direction of the optical disk DK. The focal position of the elongated optical spot at the rear side in the moving direction is matched to the recording surface of the optical disk DK and the focal position of the optical spot at the front side in the moving direction is shifted from the recording surface of the optical disk DK, whereby the light intensity of the optical spot at the front side in the moving direction becomes smaller than the light intensity of the optical spot at the rear side in the moving direction. A media ID is recorded on the optical disk DK by using the optical spot thus set.
