摘要： Apparatus for sealing the internal spindle motor bearing structure from the surrounding environment in a hard disc memory device. The motor includes a single low-cost part that seals both airflow paths, including both the bearings of the motor and around the wires. This single part acts as the electrical connector for the spindle motor as well as the seal. The invention consists of a single injection molded plastic connector with electrical contact members contained therein. Wires from the internal windings of the spindle motor pass through a hole provided in the connector housing and are terminated to the electrical contact members located within the connector. This hole is in turn sealed with a single drop of adhesive that is cured under the application of ultraviolet light. In a preferred embodiment, the spindle motor housing and connector are designed to form a press fit between the outer diameter of the circularly shaped connector housing and a groove in the motor housing provided for this purpose.

摘要： A disk drive in which a movable latch locks the data transducer assembly to prevent movement due to shock. The movable latch cooperates with an actuator by engaging an actuator extension arm. The movable latch also engages a stationary magnet with one of two latching magnets. The movable latch arm is mounted to a shaft which extends into a sealed casing which incorporates a plunger. The plunger is located in a chamber filled with viscous fluid which is not subject to migration or outgassing from the chamber. The viscous fluid provides resistance to sudden movements of the plunger. Latch release is achieved by application of low continuous force to the actuator arm by a voice coil motor.

The pivot mechanism has a bearing cartridge that supports the E-block and which pivots about a pivot shaft which supports a pair of ball bearings of the bearing cartridge. Each of the ball bearings contains only three balls that are evenly distributed circumferentially about the pivot shaft. Contact surfaces of the bearing outer race and inner race provide single-point contact between the races and the balls.

摘要： A passive actuator latching system in which a magnetic latch mechanism is mounted on an air damping mechanism. The air damping mechanism is optimized to the moving mass of the actuator and the specified mechanical shock tolerance to allow a relatively weak magnetic latch to resist unlatching due to relatively large short-duration mechanical shocks by providing damped compliance to the latching system during the application of mechanical shocks, and attenuating the shock force experienced at the magnetic interface. Various mechanisms for selecting the direction and magnitude of the damping of the compliance are disclosed.

摘要： A low noise spin motor for use in a disk drive includes two bearings having different inside diameters, different outside diameters, and preferably the same size balls. The balls in the larger bearing travel at a faster speed thereby increasing the noise frequencies and resonant frequency as compared to the smaller frequency whereby the noise from the two bearings is not compounded. A small and compact disk drive using the spin motor is described.

摘要： An apparatus and method for securing an information storage disc within a disc drive. A disc drive spindle motor assembly including a spindle and a hub portion extending radially outward from the spindle, the hub portion defining a top surface. An information storage disc is mounted on the hub portion, the information storage disc having a top surface. The assembly further includes an annular disc clamp forming a central aperture having a middle annular raised portion, an outer annular periphery portion, and at least one inner centering portion including an inner vertical peripheral surface. The central aperture of the disc clamp is sized to receive the spindle to allow the inner centering portion to center the disc clamp about the spindle, while the outer periphery engages the top surface of the information storage disc, and the middle annular raised portion extends above the top surface of the hub portion and is adapted to receive a downwardly directed force. A disc clamp retainer applying this force is connected to the spindle. The disc clamp retainer is fastened to the spindle and engages the middle annular raised portion of the disc clamp to transmit this force through the outer peripheral portion to the disc.

摘要： A dual-stage actuation assembly for a disc drive includes a movable actuator arm and a load beam connected to the actuator arm. A pad is attached to the load beam, and a hinge extends from the pad. A microactuator cradle is attached to the pad by the hinge, and includes a slider support structure having first and second beams that are bendable in response to control signals and a gimbal attached to the slider support structure for supporting the slider between the first and second beams over a surface of a disc. A first piezoelectric element is coupled to the first beam for bending the first beam in response to control signals in a selected direction, and a second piezoelectric element is coupled to the second beam for bending the second beam in response to the control signals in the selected direction. Bending of the first and second beams causes the microactuator cradle to rotate with respect to the pad about the hinge in a plane generally parallel to the surface of the disc, thereby effecting high resolution displacement of the transducing head carried by the slider.

摘要： A method and apparatus for providing cross track positioning of a disk drive head relative to a formatted track on a disk platter. A load beam is attached via a living hinge to a cradle. Piezo crystals are mounted on the cradle in plane with the load beam. The crystals are attached to levers formed into a proximal end of the load beam and activated with electric signals from a microactuator control to elongate or contract. Activated simultaneously the crystals exert a push force on one lever and a pull force on the other lever causing the load beam to pivot about the living hinge acting as a fulcrum. The load beam is attached to the cradle via cradle panels located at the distal end portion of the load beam. The cradle panels are preferably perpendicular to the load beam thereby providing low resistance in the cross rack direction and support in the vertical direction.
