摘要： In a digital signal information reproduction apparatus such as a compact disk player and a digital audio tape deck, the digital information recorded on a recording medium is read therefrom at a speed higher than usual during a first predetermined time period from the start of the read operation and at the usual speed for the remainder of the read operation. The read-out information is stored in a memory (such as a RAM), and the information stored in the memory is read out and reproduced at the usual playing speed. The information is thus read from the recording medium during a period shorter than the period required for the playing operation. The time between completion of reading the information from the recording medium and completion of the playing operation can be efficiently used for exchange of the recording medium so that when the playing operation is completed, a new recording medium is already loaded on the apparatus, thus enabling, e.g., continuous playing of pieces of music stored on a compact disk or digital audio tape.

摘要： An optical disc device of the present invention comprises an insertion detection optical sensor which detects insertion of an optical disc based on light emitted from a first light emitting element to a first light receiving element being blocked, and an ejection detection optical sensor provided on the downstream side in the carry-in direction to the insertion detection optical sensor to detect ejection of the optical disc based on light emitted from a second light emitting element to a second light receiving element being blocked. The optical disc device is structured such that, in a state that the optical disc is attached onto the turntable, when the light of the first light emitting element is blocked and the light of the second light emitting element is not blocked, the optical disc device recognizes that a lens cleaner is attached onto the turntable as the optical disc, and the optical disc device performs a cleaning operation.

摘要： In a disk loading apparatus of the present invention, a tray storage section for storing in a stacked manner a plurality of trays on which a tray is to be placed is disposed in the front side of the apparatus, and a reproduction device is disposed in the back side of the disk loading apparatus. A tray at the lowest position among the trays stacked in the tray storage section is transferred to a reproduction position by a tray driving mechanism which is operated by a single driving source. A disk which has been reproduced is returned onto a tray at the highest position in the tray storage section so that the stacked trays are sequentially circulated between the tray storage section and the reproduction device.
