摘要： An erasing beam (B1) and a recording beam (B2) emitted from a laser diode array (20) are focused on different tracks of an optical magnetic disk (D). The erasing beam (B1) is focused on a track located ahead of a track on which the recording beam (B2) is focused. The reflected beams of the erasing beam (B1) and the recording beam (B2) are separated respectively into two polarised components by a polarised beam splitter (17) and the polarised components are received by photosensors (23,24). Based on outputs of the photo sensors (23,24), an address signal, a focus error signal and a tracking error signal are obtained. At the time of reproduction, the laser diode array (20) emits a reproducing beam so that the photo sensors provide a reproducing signal.

摘要： The pick-up arms (34,36,37) are pivoted in a block (33) attached to the disc player frame. A beam of light from a laser enters the arm along the pivot axis (M) from above, and is deflected horizontally along a prismatic rod (35) to be focussed (38) onto the underside of the rotating disc (31). Light reflected from the disc passes back along the rod and leaves the arm along the pivot axis (M). The free end of the arm carries a focussing coil (3a) which moves in the air gap of a permanent magnetic assembly.

摘要： The present invention relates to an apparatus for recording and reproducing holographic data, which can record or reproduce holographic data at high speed. The apparatus includes a light source; a shutter which transmits or blocks light generated by the light source; a light splitter which splits the light transmitting the shutter into signal light and reference light; a spatial light modulator which records data on a recording medium by modulating the signal light; and a reflector which reflects the reference light to the recording medium. The shutter includes a first shutter having a first hole, and a second shutter arranged to face the first shutter and having a second hole. The shutter can block light by moving the first shutter in a first direction and moving the second shutter in a second direction, and can transmit light by moving the first shutter in a second direction and moving the second shutter in a first direction.
