摘要： A transducing head has an air bearing surface and includes a top shield, a bottom shield, a read sensor, and a first flux guide. The top shield has both a substantially rectangular non-recessed portion and a substantially rectangular recessed portion. The non-recessed portion of the top shield extends from the air bearing surface to the recessed portion of the top shield and has a thickness greater than a thickness of the recessed portion of the top shield. The bottom shield has both a substantially rectangular non-recessed portion and a substantially rectangular recessed portion. The non-recessed portion of the bottom shield extends from the air bearing surface to the recessed portion of the bottom shield and has a thickness greater than a thickness of the recessed portion of the bottom shield. A length of the non-recessed portion of the top shield is substantially equal to a length of the non-recessed portion of the bottom shield. The read sensor is positioned between the recessed portions of the top and bottom shields. The first flux guide is positioned between the top and bottom shields and extends from the air bearing surface toward the read sensor.

摘要： An energy absorbing disc travel limiter which not only mechanically defines a limit to the extent to which a disc in a disc drive can be axially displaced in response to applied mechanical shocks, but which also acts to damp the shock-induced motion of the discs, thus preventing contact between the discs and the actuator head mounting arms. The amount of damping provided by the disc travel limiter is determined by selection of the material of the disc travel limiter and selection of certain dimensions of the disc travel limiter.

摘要： An information handling system, such as a disk drive, including a base, a disk stack rotatably attached to the base, and an actuator assembly movably attached to the base. The actuator assembly also includes a load spring and a slider attached to said load spring. The slider and load spring are attached to form a gimballing connection between the slider and the load spring. The slider includes an air-bearing surface which has a contact area. The slider also includes a transducer. The transducer is typically located near said contact area. The contact area includes a roughened surface portion and a smooth surface portion. The smooth surface portion is adjacent the transducer. The roughened surface portion is rougher than the smooth surface portion. The roughened surface portion is also rougher than the other surfaces associated with the air-bearing surface of the slider. The roughened surface portion of the contact area is formed by one of several techniques. One of the techniques uses a wet etch to remove at least one of the phases of a multi-phase material. Another technique defines the area to be roughened using photolithography. After exposing the photoresist using either a mask or a laser, a portion of photoresist is removed and the areas unprotected by photoresist are dry etched to form the roughened contact area.

摘要： A gimbal formed integral with a load beam by through etching a H pattern at the end of the beam to define a pair of tabs connected by a pair of beams; half etching from the head direction one tab with an defined area masked to form a load button; and half etching the beam from the other direction to provide the proper gimbal stiffness. In practice, the head is glued to the other tab and load is applied through the button.

摘要： Apparatus and method for simultaneously biasing multiple magneto-resistive read elements in a disc drive head/disc assembly. A preamplifier circuit sequentially applies read bias currents to successive pairs of heads of the head/disc assembly, wherein the read bias current applied to a selected one of each pair of the heads is used to transduce the servo data from the associated disc recording surface, and the read bias current applied to the remaining one of each pair of the heads is used to prepare the remaining one of each pair of the heads to subsequently transduce the servo data from the associated disc recording surface. The preamplifier circuit includes at least first and second read bias current sources and a head selection circuit.

摘要： An inertial spring latch with a contact post is disclosed for use in latching an actuator assembly of a data storage device. The actuator assembly includes a contact arm that cooperates with the contact post to restrict movement of the actuator assembly when the data storage device is in a non-operating mode. The inertial spring latch comprises a latch body adjacent the actuator assembly, a forward arm extending in a first direction from the latch body and a spring member extending from the forward arm, the spring member supporting the contact post. The contact post inhibits movement of the actuator assembly by decelerating the movement of the actuator assembly upon impact of the contact arm with the contact post. Both the contact post and the spring member deflect to dampen the energy of motion of the actuator assembly upon impact of the contact arm with the contact post.

摘要： A compressive limit stop for limiting travel of an actuator assembly of a data storage device is disclosed. The compressive limit stop separates a first pole piece from a second pole piece of the data storage device, each pole piece adjacent the actuator assembly, the compressive limit stop comprising a rigid body with a top flange adjacent the second pole piece and a bottom flange adjacent the first pole piece, an inner portion having a diameter less than the diameter of the top flange disposed between the top and bottom flanges forming a channel between the flanges and a compressive sleeve with an inner wall adjacent each flange while enclosing the channel to form a gap between the inner portion and the inner wall. The compressive sleeve deflects and compresses between the actuator assembly and the inner portion to decelerate movement of the actuator assembly.
