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 disk apparatus according to the present invention includes: a light emission section for emitting laser light; an optical system for irradiating the optical disk medium with the laser light; and an aberration control section for controlling aberration of the laser light. In one embodiment, the aberration control section repeatedly switches between a plurality of aberration setting states in a focus lock-in operation. In another embodiment, the aberration control section simultaneously sets a plurality of aberration setting states in a focus lock-in operation. As a result, a plurality of aberration setting states can be allowed to substantially coexist within a single optical system.

摘要： An optical head device according to the present invention includes a splitting section for splitting a light beam having been reflected from an optical storage medium. The splitting section includes: a first main region transmitting a first interfering portion; a second interfering portion transmitting a second main region; and first and second sub-regions through which the first interfering portion is transmitted with a lower rate than in the first main region and through which the second interfering portion is transmitted with a lower rate than in the second main region. The splitting section splits the reflected light beam into: a first main light beam transmitted through the first main region; a second main light beam transmitted through the second main region; a first sub-light beam transmitted through the first sub-region; and a second sub-light beam transmitted through the second sub-region. The splitting section further includes a swapping section for swapping a portion of the first sub-light beam with a portion of the second sub-light beam.
