摘要： A disk drive includes a base, a spindle motor coupled to the base, a disk mounted on the spindle motor, a pivot assembly coupled to the base, and a head stack assembly. The head stack assembly includes an actuator body defining a bore for surrounding the pivot assembly, a supporting surface, and an actuator arm cantilevered from the actuator body and defining a longitudinal axis. The bore defines a pivot axis of the head stack assembly. The pivot assembly includes a stationary member coupled to the base, the stationary member having a length, and a rotatable member positioned on the supporting surface such that the rotatable member is between the stationary member and the supporting surface. The stationary member and the rotatable member define a projecting member and a recessed portion, the projecting member and the recessed portion interacting to allow the head stack assembly to pivot about the pivot axis. The projecting member defines a knife edge extending parallel to the length and facing in a direction substantially perpendicular to the longitudinal axis.

摘要： A disk drive includes an inner frame that has a disk drive base and a disk drive cover. A disk, mounted on a rotary spindle attached to the disk drive base, defines a disk outer periphery that protrudes into a first side opening of the inner frame. A head actuator is attached to the disk drive base and to the disk drive cover. An outer enclosure includes an extruded hollow cylinder with a cross-sectional shape that is a continuous and unbroken ring that is substantially rectangular, and that surrounds a cavity. The outer enclosure surrounds the disk drive base and the disk drive cover. During assembly, the inner frame may be slid lengthwise into an open end of the outer enclosure, and the outer enclosure may be hermetically sealed to enclose air or helium in the cavity.

摘要： An electromagnetic read/write system includes a contact interface formed by a pole-structure-carrying wear pad and a recording surface. The uppermost portion of the recording surface is characterized by a buffed, generally planarized topography. Lower elevations of the recording surface may be texturized or untexturized. Various methods of producing such an interface are described. The interface of the present invention provides dramatically improved longevity, i.e, wear performance through long term read/write operation.

摘要： The invention resides in a magnetic disk drive having a load beam assembly that forms a part of a head gimbal assembly and head stack assembly in a magnetic disk drive.The load beam assembly is uniquely mass balanced to prevent head slap by preventing an acceleration in the Z-direction from causing the transducer head to separate from the disk. The load beam assembly is preferably mass balanced by providing a load beam balancing member that is rigidly connected to the elongated load beam about a transverse axis of the hinge member. The balancing member can form the balancing mass or the balancing member can carry a discrete balancing mass. The balancing member may be divided into two halves that move on either side of the base portion, but is preferably comprised of a narrow, centrally located member that moves within an aperture formed in the base portion. The mass balanced load beam assembly can beneficially be manufactured from the same stainless steel sheets used to form conventional load beam assemblies. The balancing member may also be flexibly connected to the load beam by a spring hinge having a spring constant which, in concert with the mass of the balancing member, makes the balancing member oscillate in opposition to the disk to actively bias the head against the disk following a shock event.
