摘要： Stable tracking control is achieved for an optical recording medium having a plurality of information recording planes. To achieve this, an optical information device comprises a light source for emitting a light beam, a focusing unit for converging the light beam emitted from the light source onto a predetermined information recording plane of an optical recording medium having a plurality of information recording planes, a beam splitting unit for splitting the light beam reflected by the optical recording medium, and a light detection unit having a light receiver that receives the light beam split by the beam splitting unit, for outputting a signal corresponding to the light intensity of the light beams received by the light receiver. A guide groove is formed on at least one of the information recording planes, and the light receiver is entirely disposed within in a map formed on the light detection unit by the light beam reflected by an information recording plane other than the predetermined information recording plane.

摘要： An optical disc apparatus includes a control section. The control section performs a first search while the tracking control is in the off state. The first search is for searching for a plurality of sets of the focus positions of the light beam and the spherical aberration amounts such that an amplitude of the tracking error signal is greater than a predetermined value. The control section performs a second search while the tracking control is in the on state. The second search is for determining a set of the focus position of the light beam and the spherical aberration amount such that the reproduced signal quality index is substantially optimal, among the plurality of sets of the focus positions of the light beam and the spherical aberration amounts obtained in the first search.

摘要： An optical pickup head apparatus comprises a first coherent light source for emitting a coherent light serving as a main beam, and a second coherent light source for emitting a coherent light having a polarized plane at a right angle to the polarized plane of the coherent light emitted from the first coherent light source. When the coherent light emitted from the second coherent light source is incident upon a phase plate, the phase plate yields a sub-beam presenting a distribution of light intensity having peak values at at least both sides of the center of the sub-beam on a plane vertical with respect to the optical axis of the coherent light. Focusing means overlaps the main beam emitted from the first coherent light source on the sub-beam emitted from the phase plate, causing the resulting overlapped beam to be focused on the information-recorded surface of an optical disk. When a focused beam as reflected from the information-recorded surface of the optical disk is incident upon polarized beam separating means, the polarized beam separating means yields the transmitted beam as divided into the main beam and the sub-beam. Optical detecting means individually detects and supplies the light intensities of the main beam and the sub-beam emitted from the polarized beam separating means.
