摘要： A hologram reproduction apparatus and method is disclosed wherein positioning between reproduction reference light and a hologram recording medium can be performed accurately. Reference light is irradiated upon the medium recorded by angle multiple recording, and reproduction light generated from the medium is received by an image pickup apparatus to reproduce data. Thereupon, projection information of light which cannot pass through an iris but is projected on the iris is detected by an optical detector. A position control section detects a positional displacement of the medium based on projection state information on the inner side of a projection region of reproduction light generated from an adjacent recording area to the recording area of a reproduction target from within the detection information and controls a drive mechanism to move the medium so as to eliminate the positional displacement.

摘要： Disclosed is an optical disc device that is able to increase accuracy in reproducing information from an optical disc. The optical disc device 10 calculates a focus error signal SFE2 and a sum signal SS1 while reciprocating an objective lens 21 in a focus direction until a distance between a focal point FS and a focal point FM1 becomes close to the depth d of a target position PG at the time of a pull-in operation, and when a trigger signal ST1 generated on the basis of the sum signal SS1 is at low level, starts focus control on the basis of the focus error signal SFE2. Therefore, focus control can start in a state where the focus error signal SFE2 curves in an S shape with sufficient amplitude.
