摘要： A holographic information recording and/or reproducing apparatus, including a light source to emit light; a polarization forming optical system to form a polarized signal beam and a polarized reference beam from the light emitted from the light source, wherein the polarized signal beam and the polarized reference beam are incident on a holographic information storage medium through an identical surface; a focusing optical system to focus the polarized signal beam and the polarized reference beam onto in the holographic information storage medium so that information is recorded by an interference pattern; and an adjustment optical system to set the focal positions of the polarized signal beam and the polarized reference beam, and to adjust a difference between a path of the polarized signal beam and a path of the polarized reference beam.

摘要： A card support means is reciprocally moved by card drive means (109; 511) in a first direction. Optical heads (103; 503; 603) are reciprocally moved by head drive means (108; 507) in a second direction which is at right angles to the first direction. Motors in the drive means are surrounded by metallic vibration isolators (321, 323) and a rubber vibration isolator (322). Position of the optical card is determined by a pressing means (423) for urging the upper surface of the optical card downwardly and by a positioning means (425) capable of contacting the side surface of the optical card. The optical card inserted from the external side is placed in position by a roller means (506) which has a tilted rotary shaft. (505). The optical head (103) is usually controlled by feedback. When the drive speed has dropped, however, the open-loop control is carried out. The optical head is provided with electromagnetic drive means (833, 834) to scan the optical card. Signals read by the optical head are processed by a special binary circuit.
