摘要： An optical disc drive includes a light source and an objective optical system for condensing a light from the light source onto a recording surface of an optical disc. A chassis which is movable radially of the optical disc supports both the light source and the objective optical system. The light source includes a red/infrared unit having a red/infrared LD and a blue LD. The red/infrared LD generates both a red beam and an infrared beam. The blue LD generates a blue beam. The objective optical system includes a first and a second object lenses whose focal distances are different. The first and the second object lenses are disposed on a circumferential line of the optical disc.

摘要： A hologram recorder applies a recording beam (S) and a reference beam (R) to the illumination site (p) of a hologram recording medium (B). The interference between the recording beam (S) and the reference beam (R) produces multiple hologram recording at the illumination site (p). The recorder includes a recording-purpose reference beam reflector (10) for reflecting the reference beam (R) to the illumination site (p), and a pivot mechanism for pivoting the reflector (10) about an axis (x) to vary the incident angle (θr) of the reflected reference beam (R) to the recording medium (B). The reflector (10) is disposed to cross a predetermined optical path. The axis (x) of the pivot mechanism is so arranged that the reflected reference beam (R) is directed to the illumination site (p) even when the incident angle (θr) of the beam (R) changes due to the pivoting of the reflector (10).

摘要： A hologram reproducing device includes a splitter for splitting a reference beam, during reproduction, into a main beam and sub-beams forming incidence directions spatially shifted from the main beam. The hologram reproducing device also includes: an incidence direction variable irradiator for changing the incidence directions of the main beam and the sub-beams; a servo beam detector for detecting a portion of the reproduction beam generated in accordance with the sub-beams; and a beam receiving unit for receiving the main portion of the reproduction beam generated in accordance with the main beam. A reproducer reproduces an image obtained by the beam receiving unit when the main beam coincides with the incidence direction at which the received light of the beam receiving unit becomes equal to or greater than a prescribed level, with the intensity of the reference beam kept uniform, on the basis of the servo beam detection results.

摘要： A hologram recorder includes a signal beam irradiator to irradiate a signal beam, which is optically modulated in accordance with information to be recorded, to a recording medium at a predetermined incident angle. The hologram recorder also includes a recording prism provided with surfaces including an incident surface, a reflective surface and an emission surface for light so that a recording reference beam is guided to the recording medium by way of these surfaces. A pivot mechanism of the hologram recorder causes the recording prism to pivot above the recording medium for changing the incident angle of the recording reference beam at the recording medium, with the recording reference beam kept to overlap the signal beam.
