摘要： An optical recording medium that permits high density recording and only needs a recording machine of simple structure, and a machine for reproducing recorded information from such optical recording medium. A track pitch of recording tracks is smaller than a diameter of a beam spot of a scanning laser beam, and tracking pits for tracking control are formed on the respective recording tracks. A certain number of neighboring recording tracks define a group, and in each group the tracking pits are spaced from each other in a recording track direction by a predetermined interval which is smaller than the diameter of the beam spot.

摘要： In a optical head, a beam is emitted from a light emitting element in which a plurality of light sources are integrally formed, the light sources being able to emit beams having different wave lengths from one another. An optical system converges the beam coming from any one of the light sources onto an optical information storage medium. An optical separator separates a reflected beam coming from the optical information storage medium from the beam coming from the light source. A light receiving element detects light quantities of the reflected beam separated by the optical separator.

摘要： In a photodetector, the minimum size of the photodetection area for detecting a focus error signal from a light beam on the inner radius side of a hologram is made smaller than the minimum diameter of diffracted light beam spots (30, 31) for recording and reproduction, and when a CD is reproduced, a light beam close to the optical axis is made to significantly contribute to the focus error signal and the minimum size of the photodetection area for detecting the focus error signal from a light beam from the peripheral side of the hologram is made larger than the minimum diameter of diffracted light beam spots (130, 131) for recording and reproduction, whereby the focus error signal is made equal to the normal focus error signal when a DVD is reproduced, so that the focus offset variation caused when the base material thickness varies can be reduced.

摘要： A disk playback apparatus such as a CD player comprises a case and a lift unit which is supported to be movable in the vertical direction to the case. The lift unit comprises a playback unit, a turntable, a holder drawing member, and the like. A magazine which is adapted to be loaded in the case accommodates therein disk holders, each of which hold one of different-sized disks. A control link having a holder butting pin and a disk control pin is movably mounted on the playback unit which is urged in the direction of departing from the disk by means of a release spring. When the disk holder reaches its accommodation position, the disk holder butts against the holder butting pin and rotates the control link slightly, thereby the disk control pin compulsively corrects the position of the disk. Thus the disk is certainly transported to the normal chucking position on the playback unit irrespective of the disk accommodated state in the disk holder.

The driving block 45 is provided with a loading pinion 50 which rotates according to the output of a loading motor 47. While the transporting plate 43 makes one reciprocal movement to perform extracting returning operation of the disk holding member 11 by certain rotation control of the loading pinion 50, via the rack 43a, the loading gear 54 is rotated 180° and the chucking plate 44 is driven on the going path or the returning path to perform chucking operation or chucking disengagement operation.

摘要： A memory device has a ferroelectric memory cell block, which is connected via an input/output latch buffer to a data input terminal. The memory device also has a writing period forming circuit that forms a predetermined number of writing periods when writing of data is requested. During the thus formed plurality of writing periods, a control circuit controls the input/output latch buffer to write data to the memory cell block. Thus, a single request for writing of data causes writing of data to be repeated a plurality of times automatically.
