摘要： A connecting member connects a pair of holder plates toward the end of the holder plates at the recessed end in the direction in which the disk is inserted. By forming the holding member holding disks using three pieces, there is less deformation causes by high temperatures compared to integrally formed units. Also, since this connecting member only serves to connect the pair of holder plates, a thin rod-shaped connecting bar can be used. This allows the clearance between the disks held toward the back of the device and the rear panel to be minimized, thus contributing to a reduced depth dimension for the device.
摘要翻译：连接构件沿着插入盘的方向的凹入端将一对保持板朝向保持器板的端部连接。通过使用三块形成保持构件保持盘，与整体形成的单元相比，由于高温而导致较小的变形。此外，由于该连接构件仅用于连接一对保持板，因此可以使用薄的杆状连接杆。这样可以使保持在设备背面和后面板之间的光盘之间的间隙最小化，从而有助于减小设备的深度尺寸。

摘要： A disk memory drive includes a brushless drive outer rotor motor having an internal space and a stator with windings. The outer rotor coaxially encircles the stator and a substantially cylindrical air gap is defined between the stator and the rotor. The rotor includes permanent magnets and a hub fixedly connected with the magnet. A disk mounting section is provided on the hub for accommodating at least one storage disk positioned in a clear space, the mounting section being adapted to extend through a central aperture of the storage disk. The windings and the magnets interacting with the windings are disposed for at least half of the axial longitudinal dimension thereof within a space surrounded by the disk mounting section of the hub. Bearings rotatably mount the rotor and the hub.

摘要： A disk drive having spacers to compensate for disk warpage is described. The spacers are positioned on opposite sides of a disk with each spacer contacting the disk a different radial position relative to the center of the disk. The offset contact areas result in displaced moments on the disk, with respect to each other, when the spacers are clamped to the disk. The moments generated by the clamped spacers provide a torque on a warped disk to improve its flatness.
摘要翻译：描述了具有用于补偿盘翘曲的间隔件的磁盘驱动器。间隔件位于盘的相对侧上，每个间隔件相对于盘的中心与盘接触不同的径向位置。当间隔件被夹紧到盘上时，偏移接触区域相对于彼此导致盘上的位移力矩。由夹紧的间隔件产生的力矩在翘曲的盘上提供扭矩以改善其平坦度。

摘要： A spindle for a disc drive which can be assembled without the use of adhesives is disclosed. Stator electromagnets are encapsulated in a plastic overmold. The stator is clamped to the base with a clamp spring arrangement. An offset between the stator surface and the base flange is covered by a clamp spring such that binding of the clamp spring by a fastener allows for an adjustable biasing force to secure the stator in place. The magnet and flux shield are attached to the rotor sleeve by an easily positioned retaining ring. An elastic foam washer provides a controlled force to secure the magnet and flux shield in place on the rotor. A second elastic foam washer and a shield provide a controlled biasing force to hold magnetic fluid and magnetic poles to the rotor. Bearings are laser welded to the rotor and the shaft to rotatably mount the rotor about the shaft.

A disk size determining apparatus of a multi-disk changer of the present invention, includes a turntable, a plurality of disk holders installed at same distance from the center of the turntable, each disk holder being able to hold a disk of different size selectively, and a single light-emitting element or a single photo-detecting element above or below the turntable, wherein said each disk holder has holes at same distance from the center of the turntable, each hole passing through a light-beam from the light-emitting element in order that the disk size can be determined. A manufacturing cost of a multi-disk changer can be reduced owing to usage of a single detecting sensor.

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.

A curvilinear guide member is mounted to the frame so that substantially all points along the curvilinear guide member are positioned an equal spaced distance from the curvilinear cartridge access side defined by the frame. A cartridge access device is mounted to the curvilinear guide member so that a cartridge access end of the cartridge access device is positioned adjacent the curvilinear cartridge access side defined by the frame at substantially all positions along the curvilinear guide member. An actuator system operatively associated with the cartridge access device moves the cartridge access device along the curvilinear guide member.
