    摘要： A disk cartridge having a housing in which a disk is rotatably mounted via a hub assembly. The housing includes two cover plates, each of which has a door aperture that is selectively covered by a door that is controlled by a dedicated door control assembly. When the cartridge is inserted into a disk drive, each door is opened by its respective door opening assembly such that both sides of the disk are accessible for magnetic or optical read/write operations.In the preferred embodiment, the hub assembly includes two hub halves, at least one of which includes a plurality of resilient fingers for leveling a surface of the disk when the cartridge is contained within the disk drive. At least one of the hub halves also includes a channel having a plurality of pockets formed therein such that when a spindle base having a torque transferring element is positioned adjacent to the pockets, one of the pockets is able to substantially immediately receive the torque transferring element.

    摘要： The mechanism for loading and unloading a disk cartridge uses two sliders (one on each side of a base plate), which move in opposite directions under the influence of a tiller. Each slider has a slot to receive one of the two lifting pins provided on the cartridge receiver. The movement of the sliders drives the lifting pins along the slots, thereby raising or lowering the cartridge receiver depending upon the direction of rotation of the tiller. The sliding motion of the lifting pins engaged in the S-shaped slots thus unloads a disk from or, alternatively, loads the disk onto the drive spindle. As the lifting pins travel along their respective slots, the lifting and lowering of the disk is accomplished in such a manner that the disk hub is peeled from the spindle magnet rather than being lifted vertically off the spindle. This reduces the peak force required to break the magnetic clamp force between the spindle magnet and the disk hub. In this system, the dust door is attached to the cartridge receiver, and the label end of the loaded cartridge remains visible when the disk is loaded. This system may include a bias coil assembly rotatably mounted on an arm so that the bias coil assembly may be loaded into or extracted from the disk cartridge and placed out of the travel path of the disk cartridge. The rotation of the bias coil arm is effected by one of the sliders.

    摘要： A cartridge unloading apparatus for a disk drive having a cartridge loading end, a remote end, and a base plate. The apparatus is employed for tiltably unloading the disk from a spindle magnet with a peeling action. The apparatus includes first and second sliders positioned relative the ends of the disk drive. The sliders each have only one S-shaped slot formed therein. Each slider has a slot to receive one of the two lifting pins provided on a cartridge receiver. The movement of the sliders drives the lifting pins along the slots, thereby raising or lowering the cartridge receiver depending upon the direction of rotation of the tiller. The sliding motion of the lifting pins engaged in the S-shaped slots thus unloads a disk from or, alternatively, loads the disk onto the drive spindle. As the lifting pins travel along their respective slots, the lifting and lowering of the disk is accomplished in such a manner that the disk hub is peeled from the spindle magnet rather than being lifted vertically off the spindle. This reduces the peak force required to break the magnetic clamp force between the spindle magnet and the disk hub. The apparatus may include a bias coil assembly rotatably mounted on an arm so that the bias coil assembly may be loaded into or extracted from the disk cartridge and placed out of the travel path of the disk cartridge. Methods for manufacturing and operating the apparatus in conjunction with a disk drive are also provided.

    摘要： A releasable disc adaptor for conforming the central hub of an information storage disc to a standardized magneto-optical disc drive spindle. The disc adaptor includes a hub receiving member having a center connected to a medium receiving member having a center. The centers of the medium receiving and hub receiving members are collinear. The adaptor includes a hub fastener fixedly mounted to the hub receiving member. The hub fastener is utilized to removably secure the hub receiving member to a disc drive spindle. The adaptor also includes a medium fastener connected to the medium receiving member. The medium fastener is used to removably secure the central hub of an information storage disc to the hub receiving member and prevent slippage therebetween so that the disc hub is thereby conformed to properly seat on the disc drive spindle while thereafter allowing the disc to be fully disengaged from the adaptor members for proper seating on an alternate disc drive spindle. The hub receiving member, medium receiving member, hub fastener, and medium fastener form a portable assembly that may be employed in any one of a plurality of magneto-optical disc drives.
