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： A disc drive having a pivot cartridge and an actuator assembly. The actuator assembly consists of an actuator body which has a bore therein to receive the pivot cartridge. The actuator body further consists of an opening which serves as a ledge to engage a biased retaining ring. The biased retaining ring couples onto the pivot cartridge and forces the pivot cartridge to contact against one side of the bore of the actuator body.

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： An information handling system, such as a disc drive, including a base, a disc stack rotatably attached to the base, and an actuator assembly movably attached to the base. The disc stack assembly includes a spindle hub rotatably coupled to the disc drive. The spindle hub has an axis of rotation about which the disc stack assembly rotates. The spindle hub includes a cylindrical portion. The disc stack assembly also includes a clamp, a disc spacer, and a disc coupled to a spindle hub. The disc spacer has an opening therein dimensioned to receive the cylindrical portion of the spindle hub. The disc spacer is asymmetrical and positioned to counter balance a mass offset in the disc stack assembly. The asymmetrical disc spacer also includes a registration surface. The registration surface is on the outer perimeter of the disc spacer. The disc spacer has a center of mass offset from the axial centerline of the opening. The disc spacer is used to counter the center of mass offset of the disc stack assembly. Typically, balancing the disc stack assembly requires that the center of mass of the spacer is on one side of the axis of rotation of the hub and the center of mass of the disc stack assembly is on the other side of the axis of rotation of the hub. The flat surface of the asymmetrical disc spacer is positioned so the plane of the flat surface intersects a plane defined by the axial centerline of the disc stack assembly and a point associated with the mass offset of the disc assembly.
