Abstract: PROBLEM TO BE SOLVED: To stabilize a recording/reproducing operation by setting recording laser power to an optimal condition even in high-speed rate recording. SOLUTION: For a driving pulse for driving a laser means, the level ΔP of a longitudinal pulse (overdriving pulse) and the front edge shifting amount θof the driving pulse are independently controlled variably. Even when a level in a longitudinal pulse period reaches a laser power limit, and power becomes short, the recording power can be increased by controlling of the front edge shifting amount θ or the like.

Abstract: PROBLEM TO BE SOLVED: To promote miniaturization and cost reduction by projecting a far field pattern of the reflected light which is a luminous flux obtained from a low resolution optical path forming means and focused on an optical recording medium, and outputting a light intensity difference between each light receiving signal in bisected light-receiving regions obtained by an optical system provided with a photo-detecting element with at least bisected light receiving regions. SOLUTION: If a light beam spot SPa of zero-order light forms an image on a photo-detecting element 37a, a signal of light intensity difference between the light receiving regions interposing that division line of the photo-detecting element 37a which is parallel to the tracks and passes along a center of optical beam spot is modulated in the intensity every time when crossing a track of the disk. If an objective lens moves from the center position in the radius direction of the disk, or the disk has an inclination to an optical system, the light beam spot moves, therefore, such a signal is obtained as is changed in the intensity according to a moved quantity in the disk radius direction of the objective lens or an inclination of the disk.
