摘要： An improved disk drive includes an improved operating system, an improved eject system, an improved head retract system and an improved motor loading system. In a preferred embodiment of the operating system it includes a motor, an eject crank, a head crank and an actuator. The output of the motor can be selectively controlled by the actuator to power either the eject crank or the head crank. Powering the head crank, causes the disk drive heads to move, and powering the eject crank causes a disk cartridge to be ejected from the disk drive. The motor loading system may have a disk drive motor having a threaded exterior and a member extending from the exterior to interface with the eject system. Additionally, this motor loading system may include an aperture in the chassis of the disk drive that has a threaded ring running around the circumference of the aperture and a spring extending from the threaded ring. The disk drive motor can be inserted into the aperture in the chassis with the member depressing the spring. The disk drive motor can then be rotated to mate the threads of the disk drive motor with the threaded ring. When rotated, the slotted member releases the spring. The spring prevents rotation of the disk drive motor past a predetermined point and thereby prevents the motor from becoming dislodged from the chassis. When inserted into the disk drive, the motor can be moved between a loaded and an unloaded position.

摘要： A disk drive of the type that receives a removable disk cartridge containing a disk-shaped storage medium, includes an actuator for carrying a pair of opposed read/write heads into engagement with respective opposite surfaces of the disk-shaped storage medium, and a pair of opposed projections disposed adjacent the read/write heads when they are in a retracted position. The opposed projections have opposed angled surfaces that deflect and capture the edge of the disk-shaped storage medium during cartridge insertion to prevent the edge of the storage medium from damaging the read/write heads. The opposed projections are preferably formed as part of a load ramp member that is snap-fit to another structure within the disk drive to facilitate assembly of the disk drive.

摘要： A movable platform is mounted on opposing guide rails within a disk drive. A head actuator and spindle motor are mounted on the movable platform. The platform moves on the guide rails from a forward position to a rearward position upon insertion of a disk cartridge into the disk drive. As the platform moves toward the rearward position, the elevation of the platform changes in order to bring the spindle motor into engagement with the hub of the disk cartridge. A latch member is pivotally mounted on one of the guide rails for latching the platform in its forward position when the disk drive is not in use.

摘要： A disk drive apparatus has an eject member that moves in tandem with a disk cartridge from a first position to a second position upon insertion of the disk cartridge into the disk drive apparatus. The eject member has a projection formed thereon. A first spring biases the eject member in a direction opposite the direction of insertion of the removable disk cartridge. A motor ring assembly mounted on a chassis of the apparatus has a rotating member that rotates between an unloaded position and a loaded position. A second spring biases the rotating member toward its loaded position. A spindle motor is mounted in the motor ring assembly. The rotating member has a first cam surface, a second cam surface that extends substantially perpendicularly to the first cam surface, and a lead-in cam angle surface that extends between the first and second cam surfaces at an angle thereto. A shape memory alloy wire or other means is provided to rotate the rotating member from its loaded position toward its unloaded position. As that occurs, the second cam surface of the rotating member moves past the projection on the eject member, thereby allowing the eject member to move back toward its first position under the force of the first spring. This, in turn, allows the projection on the eject member to push against the lead-in cam angle surface of the rotating member to rotate the rotating member further toward its unloaded position.

摘要： A magnetic disk drive has a linear actuator with crash stops molded in the retainer plate of the drive. The retainer plate holds various components in the drive. The crash stops include two leaves which have sufficient resiliency to absorb the impact energy of the carriage. The retainer plate has a recess at the base of the leaves which provides additional length to each leave to provide resilience, the components held by the container plate dissipate the impact energy of stopping.

摘要： A linear actuator carries read/write heads into engagement with a removable cartridge having a recording disk. The magnetic heads are mounted on a carriage which moves linearly on a central guide track. The carriage moves linearly on front and rear bearings which move on a central guide track as the magnetic motor is energized. The rear bearing is elongated in the direction perpendicular to the plane of the disk to allow movement of the carriage transverse to the direction of travel. This compensates for planar misalignment of the plane of the recording disk with respect to the axis of the central track.

摘要： There is disclosed a disk drive having a linear actuator for carrying read/write heads into engagement with a recording medium. The heads are mounted on a carriage assembly along with a voice coil motor for driving the carriage assembly into and out of engagement of the heads with the medium. The carriage assembly slides linearly on a central guide track. A flexible mounting suspension is provided for the central guide track for linear movement by the carriage assembly so that initial linear movement of the carriage assembly is by flexing the suspension and further, larger linear movement of the carriage assembly is by sliding along the guide track. In one form of the invention the central guide track is suspended at the front end by a flexure and at the rear end by a bearing. In another form of the invention the central guide track is suspended at each end by a flexure.
