摘要： An optical disc apparatus includes a withdrawal means for moving an objective lens (32) to a position distant from an optical disc (1) during an inactive duration of intermittent recording or reproducing operation. A means for regulating or fixing the objective lens (32) at the position distant from the optical disc (1) is further provided. Thus, even in a noncontrolled state during the inactive duration, it is possible to prevent collision of the objective lens (32) with the optical disc (1). As a result, both power saving and safety of the apparatus can be attained.

摘要： A collision preventive member that limits displacements of an objective lens in a focusing direction is provided. The collision preventive member includes a first limiting portion that limits displacements of the objective lens present within a first region while allowing a movable range of the objective lens in the focusing direction to overlap a deflection range of the optical disc within the first region, and a second limiting portion that limits displacements of the objective lens present within a second region in establishing a relation such that the movable range of the objective lens in the focusing direction does not overlap the deflection range of the optical disc within the second region. A controller that controls the objective lens in such a manner that the objective lens is located within the second region in a non-focusing state of the objective lens is provided. It is thus possible to prevent a collision between an optical disc and the objective lens under the environment where vibrations are applied.

摘要： When the tilt of an optical disk is detected using a light source of an optical head, the optical head cannot be simplified enough and an optical-disk tilt cannot be detected adequately. The optical head includes: an LED chip; a light-converging element that converges the light which is emitted from the LED chip upon an optical disk; a light-converging element driving means which drives the light-converging element; and a sensor which detects a tilt or a positional shift of the optical disk. In the sensor, the LED chip is placed on a semiconductor substrate which is provided with a plurality of light-receiving chips; the light emitted from the LED chip irradiates the optical disk; the light which is reflected from the optical disk is received by the plurality of light-receiving chips; and based upon the quantity of light which is received at the plurality of light-receiving chips, a tilt or a positional shift of the optical disk is detected.
