摘要： An optical disk drive which reduces the number of motors used for drive operation is thereby simplified while shock resistance, vibration resistance, and productivity are improved. A turntable, a first motor for turntable drive, an optical pickup and drive mechanism, are provided on a drive base and a separate traverse base that floats on the drive base. A loading drive mechanism drives a disk loading mechanism. A second motor can be driven in forward and reverse to supply drive power to the loading drive mechanism and a pickup drive mechanism. A drive power transfer path switching mechanism is used to switch the path through which drive power from the second motor is transferred to supply power to the loading drive mechanism and pickup drive mechanism. By continuously driving the second motor in one direction, moving the optical pickup, raising or lowering the turntable, and transporting a disk can be accomplished in this sequence substantially continuously; by reversing the direction of motor drive, these operations can be accomplished substantially continuously in reverse direction in reverse sequence.

摘要： An optical disc device, having a traverse base includes an optical pickup and a feed motor that drives the optical pickup forward and backward from an inner circumferential position of an optical disc to an outer circumferential position thereof. This device comprises a loading device for transferring an optical disc from the exterior of the device body onto the traverse base, and a loading driving device for driving the loading device by using the driving of the feed motor. The feed motor can move the optical pickup for signal reproduction and eject the optical disc to the exterior of the device, thereby reducing the number of motors used in the device to provide a more inexpensive optical disc device.

摘要： An optical pickup device featuring reduced number of components and improved workability for achieving cost reduction and improved product quality. A base stand (4) is provided with a first guide section (8) and a second guide section (9) which stand upright from the base stand individually and can slidably engage with the first and second engagement portions (11, 12) provided on a mount base (3), respectively. This arrangement permits the base stand (4) having the guide sections (8,9) fixed thereon to be assembled directrly with the mount base (3) including an optical pickup thereon, resulting in simplified assembly operation and enhanced operation efficiency. Further, integral forming of the base stand (4) together with the first guide section (8) and the second guide section (9) into one body enables it to reduce the number of components, cut the production costs and improve the product quality

摘要： An optical disc drive apparatus including a main tray having a stack of subtrays mounted thereon and movable between withdrawn and inserted positions. When the main tray is moved to the inserted position, the subtrays stacked thereon are held at a stand-by position and a selected one of the subtrays is ready to be drawn towards a loaded position so that an optical disc resting on the selected one of the subtrays can be clamped in position and optically read out. When an optical disc resting on one of the subtrays other than the uppermost subtray then held at the loaded position is desired to be removed or replaced, not only can such one of the subtray be returned from the loaded position to the stand-by position, the main tray is allowed to withdraw from the inserted position back to the withdrawn position carrying such one of the subtrays and the subtray or subtrays positioned immediately thereabove while leaving the subtray or the subtrays positioned above such one of the subtrays at the stand-by position, so that such one of the subtrays can readily be exposed to the outside for removal or replacement of the optical disc resting thereon.

摘要： For providing an optical disk driving device that is capable of accurately performing recording and reproduction of even disks that include warpage without the provision of a tilt mechanism, a clamper is comprised of a central clamper portion for pinching and holding a disk between the clamper and a turntable, and an outer clamper portion for abutting against an outer periphery of the disk and pressurizing the same in case the disk includes any warpage to thereby correct the warpage. It is accordingly possible to restrict an angle formed between a light beam and an information surface of the disk to be within a specified value for accurately performing reproduction.

摘要： An optical disk drive includes a turntable, a first motor for turntable drive, an optical pickup and a drive mechanism arranged on a drive base and a separate traverse base that floats on the drive base. A loading drive mechanism drives a disk loading mechanism. A second motor can be driven in forward and reverse directions to supply drive power to the loading drive mechanism and a pickup drive mechanism. A drive power transfer path switching mechanism is used to switch the path through which drive power from the second motor is transferred to supply power to the loading drive mechanism and pickup drive mechanism. By continuously driving the second motor in one direction, then moving the optical pickup, raising or lowering the turntable, and transporting a disk can be accomplished in this sequence substantially continuously. By reversing the direction of motor drive, these operations can be accomplished substantially continuously in reverse direction in reverse sequence.
