摘要： A miniature removable disk drive that meets the CompactFlash type II form factor and interface specifications uses a composite sheet metal/plastic tub-shaped base for supporting the disk drive components, e.g., the spindle motor with attached disk, the voice coil motor actuator with attached read/write head, and the preamplifier/write driver electronics module. The composite base is a metal plate with a flange extending around its perimeter and a plastic frame that encapsulates the flange and surrounds the perimeter of the metal plate. The metal plate supports the disk drive spindle motor and voice coil motor actuator and is made of high magnetic permeability, low coercivity material so that it can form part of the magnetic circuit of the spindle motor and/or actuator. The flanges on the metal plate provide rigidity and allow the base to be fabricated by injection molding the plastic frame onto the metal base so that the plastic encapsulates the metal flanges to form the walls of the tub-shaped base. An electronics card is located beneath the metal plate and is electrically shielded from the read/write heads and electronics module by the metal plate. Top and bottom covers are attached to the frame to enclose the disk drive components and the electronics card. Because the frame is made of plastic the corners may be made with intricately shaped cutouts that allow elastomeric corner bumpers to be interlocked into the frame at the corners. The corner bumpers extend beyond the frame and the covers so as to provide shock protection if the miniature removable disk drive is dropped.
摘要翻译：符合CompactFlash II型外形尺寸和接口规格的微型可移动磁盘驱动器使用复合金属/塑料桶形基座来支撑磁盘驱动器组件，例如带有附加磁盘的主轴电机，附带的音圈电机执行器读/写头，以及前置放大/写入驱动器电子模块。复合基座是具有围绕其周边延伸的凸缘的金属板和塑料框架，其封装凸缘并且围绕金属板的周边。金属板支撑磁盘驱动器主轴电机和音圈电机执行器，并由高磁导率，低矫顽力材料制成，从而可以形成主轴电机和/或执行器的磁路的一部分。金属板上的凸缘提供刚性并允许通过将塑料框架注塑成金属基底来制造基座，使得塑料封装金属法兰以形成盆形基座的壁。电子卡位于金属板下方，并通过金属板与读/写头和电子模块电隔离。顶盖和底盖连接到框架以封闭磁盘驱动器组件和电子卡。由于框架由塑料制成，所以角部可以形成为具有复杂形状的切口，其允许弹性角部保险杠在拐角处与框架互锁。拐角缓冲器延伸超出框架和盖子，以便在微型可移动磁盘驱动器掉落时提供冲击保护。

摘要： A disk drive includes a data storage disk rotatably mounted in a housing. An access arm is rotatably mounted in the housing and has an access head at a distal end thereof for travel over the disk to write data thereto and read data therefrom. A pair of counter imbalanced inertia locks are operatively joined between the housing and the access arm for inertia latching the access arm upon shock loading of the access arm to prevent movement thereof over the disk irrespective of combinations of linear and angular shock loading.

摘要： A disk drive includes a data storage disk attached to a spindle which is rotatably mounted to a housing. A support shaft is also mounted to the housing parallel to the spindle, and includes an arm supported thereon parallel to the disk. A rib extends along the housing between the spindle and the support shaft for synchronizing fundamental resonant vibration thereof due to a shock load to couple in phase vibratory motion thereof. The support shaft may pivot and carry a suspension arm and data access head, or the shaft may be stationary and carry a load-unload ramp for parking the suspension arm, or both types of shafts may be used in the housing with corresponding ribs extending to the common spindle.

摘要： A data storage device 12 includes a disk 14 having a surface zone 14a for storing data, and an access head 18 mounted on a slider 20 for writing data to and reading data from the data zone. The head 18 flies across the data zone 14a to access selected data tracks during spinning of the disk. And, the slider 20 seeks a predetermined shock buffer zone 30 atop the spinning disk, where critical data is not stored, during an idle mode for confining thereto any shock induced contact between the slider and disk surface.

摘要： A method and system for overcoming force which inhibits movement of a data storage device are provided. The invention includes generating momentum in a moveable member and then utilizing the momentum of the moveable member to generate a large impulse force on a stationary body (e.g., the data storage device) to overcome the movement-inhibiting force thereon. This is accomplished by allowing the moveable member to move along a trajectory independently of the stationary body, thereby building momentum in the moveable member. The subsequent impact of the member on the body overcomes the force. The moveable member can then also be used, in one embodiment, to continue driving the body during system operation.

摘要： A technique for preventing damage to ball bearings in small form factor devices where the drive motor has at least one piezoelectric crash stop ring disposed about the shaft and inside the rotor of the motor. The crash stop ring must be dimensioned to permit only a small amount of movement of the rotor relative to the shaft. The permitted movement is less than the minimum movement which would cause damage to the elements of the ball bearing.
