    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.

    摘要： Disclosed is 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 flexure 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 flexure 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. The flexure has an attaching mechanism for attaching the flexure to the central guide track so that the flexure pivots freely on the central guide track. This eliminates the likelihood of bending of the central guide track and improves the ability of the system to reject 1f and 2f run out and therefore, track following.

    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 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.

    摘要翻译： 磁盘驱动装置具有将磁盘盒插入磁盘驱动装置时与盘盒一起从第一位置移动到第二位置的弹出构件。 弹出构件具有形成在其上的突起。 第一弹簧沿与可移动盘盒的插入方向相反的方向偏压弹出构件。 安装在该装置的底盘上的电动机环组件具有在卸载位置和装载位置之间旋转的旋转构件。 第二弹簧将旋转构件偏压到其装载位置。 主轴电机安装在电机环组件中。 旋转构件具有第一凸轮表面，大致垂直于第一凸轮表面延伸的第二凸轮表面，以及以与其成角度在第一和第二凸轮表面之间延伸的引入凸轮角度表面。 提供形状记忆合金线或其他装置以使旋转构件从其装载位置朝向其卸载位置旋转。 这样，旋转构件的第二凸轮面移动经过弹出构件上的凸起，从而允许弹出构件在第一弹簧的力作用下向其第一位置移回。 这反过来又允许弹出构件上的突出部件推动抵靠旋转构件的引入凸轮角度表面，以使旋转构件进一步朝向其卸载位置旋转。
