Abstract: A method, apparatus, and a disk file for adjusting the height of a set of load/unload lift cams with respect to the axial height of an associated stack of disks. The method steps comprise supporting load/unload lift cams with an adjustment tool, measuring the relative height of the load/unload lift cams with respect to the stack of disks in the axial direction with a non-contact transducer, and fixing the load/unload lift cams at a registered height with respect to the stack of disks.

Abstract: A diaphragm isolator frame for supporting a disk drive in a rack or other enclosure while providing isolation from undesirable vibrations from other disk drives or components mounted in the enclosure or from the environment. The diaphragm isolator frame comprises a pair of side rails having isolators formed of thinned portions of the side rails to form diaphragms, each diaphragm having a centrally located press-pin for supporting the disk drive. The thickness and diameter of the diaphragms may be chosen to provide vibration isolation at a desired frequency.

Abstract: An interlocking disk apparatus for preventing disk slip in a disk stack of a magnetic or optical disk drive is provided. A textured region within the inner diameter of the disks in the disk stack is forced in tight contact with a conformable adjacent surface, such as a spacer ring, clamp plate, and/or hub flange. The textures on the disks penetrate into and/or through the conformal coatings on the adjacent surfaces, resulting in mechanical interlock that inhibits in-plane displacements of the disks from shock and generally improving interfacial contact of the surfaces within the disk stack, thus requiring lower clamping pressures to the disk stack and resulting in greater disk flatness and minimizing disk distortion. Electrostatic Discharge within the disk stack is prevented by diffusing conductive materials into the polymer conformal coating to increase its electrical conductivity.

Abstract: A retention and retraction device for a slider and suspension in a magnetic disk drive. A cam actuation device is placed at the outer periphery of each disk in a disk drive having a multi-disk stack. A cam surface attached to a load beam that is part of the suspension engages the finger when the actuator arm is rotated far enough toward the outer periphery. The finger displaces the cam and attached suspension. In turn, a slider attached to the suspension is moved away from a disk surface over which it had been engaged in a flying relationship.

Abstract: A disk drive has at least one disk for storing data and at least one transducer for reading or writing data to or from the disk. The transducer is attached to an actuator which positions the transducer with respect to the disk. The actuator includes a controllable motor which is used to move the actuator and the transducer attached thereto. The disk drive also includes a ramp for off loading the transducer or for parking the transducer off of the surface of the disk. The disk drive includes a combination shock absorber and gasket that has locking tabs to keep the combination shock absorber and gasket in place during a shock or impact loading event. The combination shock absorber and gasket also can be provided with additional extensions to lessen shocks caused by flat drops. Elastomeric blocks or pads can be provided on the cover and the base to lessen shocks caused by flat drops.
