摘要： An optical disc apparatus arranged so that a light beam from a laser light source is focused by an object lens and irradiated on an optical recording medium having thereon a mirror surface and tracks of a plurality of pits for recording data, and that a reflected beam from the recording medium is irradiated on an optical detector from which a signal on the recording medium is reproduced for maintaining a position of said object lens at an optical center axis by a tracking servo. The optical detector includes at least two adjacent photoelectric transducers providing outputs indicative of the reflected beam incident thereon, a device for producing a signal indicative of a difference between the outputs from the transducers, and a position detector for detecting the position of the object lens in a direction perpendicular to the tracks in cooperation with said difference producing device. The position detector includes a sampling arrangement for sampling the difference signal when the light beam is irradiated only on a non-pit portion of said mirror surface. Further, the optical detector includes a feedback loop for positioning the object lens at the optical center axis when the tracking servo is not properly operated at the time of accessing or by external disturbance.

摘要： An method to prevent excessive heat generation of the pickup actuator from occurring when a disk has a large eccentricity or planar vibration in a high-speed disk reproducing apparatus using an optical pickup. The disk reproducing apparatus has a status determining arrangement for monitoring a present actuator drive state, an analyzing arrangement for analyzing an output signal of the status determining arrangement, and disk rotational speed switching control arrangement for selecting disk reproducing speeds according to a control signal of the identification means, thereby lowering the reproducing speed when the eccentricity or planar vibration is large. Such invention prevents heat generation of the pickup actuator from occurring because high-speed reproduction can be performed when the eccentricity or planar vibration is small, and reproduction speed can be automatically reduced when the eccentricity or planar vibration is large.
