    摘要： An optical information processing apparatus includes: an optical head for radiating a light beam onto an information storage medium and generating a reproduction signal from the light beam reflected an/or diffracted from the information storage medium, the information storage medium carrying optically readable information recorded thereon; a transportation member for causing a relative movement of the optical head with respect to the information storage medium; and a signal processing circuit for receiving the reproduction signal generated by the optical head and processing the reproduction signal. The reproduction signal obtained from the information storage medium irradiated with the light beam includes first information from a mark near a boundary between a region which is heated by the light beam to no less than a predetermined temperature and a first region which is at a temperature below the predetermined temperature, and second information from a mark near a boundary between the region which is heated to no less than the predetermined temperature and a second region which is at a temperature below the predetermined temperature. The signal processing circuit separates the first information from the second information, or vice versa, thereby obtaining from the reproduction signal the information recorded on the information storage medium.

    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.
