摘要： A centering, clamping, and ejection mechanism for a magnet disk drive assembly includes a disk guide slot (18) in face plate (16), a frame (12, 14, 39), and a base plate (96) providing the mounting and support for a disk drive motor (63) and drive spindle (90). A cover member (68) includes a recess (70), centered directly above the spindle (90), with inner walls (72) having helical guide slots (74) adapted to accept a rotor (78) which has mating thread portions (79). A disk inserted into the guide slot (18) engages with end stops (26, 28) of a lower link (108) which causes a pivotal handle (24) normally recessed in a second slot (22) of the face plate (16) to become accessible. Upon manual rotation of the handle (24), an upper link (38), interconnected with the lower link (108), engages a radial extension arm (43) of the rotor (78) thereby causing the rotor (78) to turn within the inner walls (72) of the recess (70). This brings a centering and clamping assembly (86) and the disk into engagement with the spindle (90) while the rotor (78) is locked in the clamped position and the handle (24) is recessed in the second slot (22) to prevent inadvertent actuation. A release button (50) can be manually pushed which forces the upper link (38), through an overcenter link (102), to rotate the rotor (78) and return the handle (24) to their respective original positions and to force the disk partially out of the disk slot (18).
摘要翻译：用于磁盘驱动器组件的定心，夹紧和排出机构包括面板（16）中的盘引导槽（18），框架（12,14,39）和底板（96），底板（96）提供安装和支撑盘驱动马达（63）和驱动主轴（90）。盖构件（68）包括位于心轴（90）正上方的中心的凹部（70），内壁（72）具有螺旋形引导槽（74），其适于接纳具有配合螺纹部分（79）的转子（78））。插入到引导槽（18）中的盘与下连杆（108）的端部止动件（26,28）接合，该下连杆（108）引起通常凹入面板（16）的第二槽（22）中的枢转手柄（24）成为可及。在手柄（24）的手动旋转时，与下连杆（108）互连的上连杆（38）与转子（78）的径向延伸臂（43）接合，从而使转子（78）在内凹部（70）的内壁（72）。这使得定心和夹紧组件（86）和盘与主轴（90）接合，同时转子（78）被锁定在夹紧位置，并且手柄（24）凹入第二槽（22）中以防止无意的动作。可以手动地推动释放按钮（50），迫使上连杆（38）通过过中心连杆（102）旋转转子（78）并将手柄（24）返回到它们各自的原始位置，并迫使磁盘部分地从磁盘插槽（18）中移出。

摘要： A disc drive (20) including a spindle motor assembly (42) having a magnetic clutch plate (46) and an actuator (47) receives a hermetically sealed cartridge (22) containing a plurality of discs (72, 74) with associated heads (80, 81) mounted in the cartridge (22). Associated with an arm assembly (84) which supports heads (80, 81) is a component (50) for use with the actuator (47). With the cartridge (22) inserted in the drive (20), the actuator (47) operates to cause the heads (80, 81) to traverse relative to the disc (72, 74) as the spindle motor assembly (42) uses a magnetic field to engage a magnetic plate (77) associated with cartridge (22) in order to spin the disc (72, 74). Data transfer connectors (52, 54) are associated with both the drive (20) and the cartridge (22) in order to allow for the transfer of data between the cartridge (22) and the drive (20).

摘要： A mechanism for clamping and spinning a flexible disk comprising a spindle (14) and a collet (16). The spindle (14) includes a guide hub (22) supported by two ball bearings (26) and (28) mounted on a fixed shaft (42). The guide hub (22) is a hollow cylinder and is rotated by a belt (92) driven by an electric motor. A precision bore (34), equal in diameter to the nominal diameter of the center hole in the flexible disk, is provided in the guide hub (22) as a reference surface for positioning the disk, and a surface (58) perpendicular to the axis of the spindle (14) is provided for clamping the disk. The collet (16) comprises two interlocking molded plastic parts, a finger ring (72) and a clamp hub (74), that are rotateable attached to a guide arm (20). The finger ring (72) includes several radially moveable fingers which form a conical camming surface (103) with a maximum diameter slightly larger than that of the guide hub bore. A surface (108) for clamping the flexible disk is provided on the clamp hub. An O-ring (76) is positioned between the finger and the clamp hub to provide a compliant stop for inward movement of the fingers.
