摘要： An actuator and a method for using an actuator in a disc drive having a limited range of rotation wherein an actuator arm for providing motion for reading or writing data to or from media engages a shaft or post fixed within the actuator arm for communicating with the actuator arm by means of clips affixed to the shaft. The clips have flexible wings affixed to the actuator arm whereby the shaft and the actuator arm are held in a fixed relationship allowing the arm to rotate with respect to the shaft while movement between the actuator arm and the shaft other than by rotation is prevented by the shape of the flexible wings.

摘要： The shock absorber apparatus for a disc drive is a molded polymeric enclosure adapted to receive and retain a disc drive. One preferred embodiment of the present invention has a shock absorbing material of a first thickness adjacent a critical region of the drive and a second thickness of shock absorbing material adjacent a non-critical region of the disc drive. The first thickness is greater than the second thickness in order to absorb a greater shock load to protect the critical region of the disc drive.

摘要： There is provided an inertial latching system which includes a first latch member configured to engage a second latch member at a junction point. The first latch member includes a latch pivot mounted to the base. One side of the latch pivot extends to form a first arm whilst a balancing mass is found at another side of the latch pivot. Joined to the first arm is a finger which provides a contact line ending in a proximal point. The second latch member has a contact surface which provides a contact point. The inertial latching system is configured such that the ratio of a first length to a second length is smaller than the ratio of a third length to a fourth length. The first length is defined as the distance from the proximal point to the junction point, the second length is defined as the distance from the proximal to the latch pivot, the third length is defined as the distance from the contact point to the junction point, and the fourth length is defined as a distance from the contact point to the actuator pivot.

摘要： Apparatus and method for mounting a disc drive with vertical and horizontal compressible elements and for stabilizing the disc drive during use. Shock mounts are affixed to a horizontal surface (i.e. parallel to a data surface) of the disc drive, slowing vertical shock pulses transmitted from the frame to the disc drive. Recessed vertical surfaces are formed on sides of the housing to accommodate additional dampeners, which slow horizontal shock pulses while reducing operating vibration.

摘要： A disc drive is provided which incorporates a rotatable actuator which is mounted to a base of the disc drive through a pivot mechanism. The actuator positioning is controlled by a servo system and during track following operations, the actuator arm is caused to move. In one embodiment, the servo tracks incorporated in the disc drive are distorted when written in by the injection of a sinusoidal signal. In another form, the disc containing the servo information is caused to rotate about an axis which is offset from the disc axis. A method of creating a servo track is also disclosed.

摘要： A method for generating a velocity command for an actuator assembly is provided. The actuator assembly includes an actuator arm, which is to move over a plurality of surfaces. The method begins by providing a compensation torque for each of the plurality of surfaces. A position of the actuator arm is determined so that it may be mapped to one of the plurality of surfaces, which is the present surface over which the actuator arm is moving. A target velocity is then provided for the actuator arm and input to a controller, which generates a velocity command from the target velocity and a selected compensation torque, which is the compensation torque of the present surface.
