A disk drive head suspension including a load beam having a load beam load point region and a flexure, attached to the load beam, having a flexure load point region. A mass of viscoelastic material is fixedly attached to both load beam load point region and flexure load point region to form a pinned load point. A method for manufacturing a disk drive head suspension of the type having a flexure with a flexure load point region on a load beam with a load beam load point region. The flexure load point region is spaced apart from the load beam load point region. A load point is formed by applying a mass of viscoelastic material to the load point region of at least one of the flexure and the load beam.

A method for mounting a head slider of the type having terminal pads to a wireless disk drive head suspension flexure including a slider mounting region, lead contact pads, and a deflectable and resilient slider engagement member for releasably mounting a head slider to the slider mounting region. The method includes engaging and deflecting the slider engagement member and positioning the head slider onto the slider mounting region and between the lead contact pads and the slider engagement member while the slider engagement member is deflected. The method further includes disengaging the slider engagement member and causing the slider engagement member to force the head slider into frictional engagement with the lead contact pads and the slider engagement member with the lead contact pads in mechanical and electrical contact with the head slider terminal pads.

An alignment tool for preparing through holes in a door to enable mounting a lock assembly includes a slidable bracket for securely positioning the tool in the mortise at the edge of the door. An angle element is connected to the bracket and to a support plate, which is perpendicularly disposed relative to the bracket. The support plate is formed with precisely positioned guide holes that indicates to the door installer exactly where the through holes are to be made.

A housing, simulating the configuration of a container such as a glass bottle, includes an internal chamber for supporting a center post having an axial bore for receiving a biaxial accelerometer electrically connected to circuitry for detecting and recording the magnitude of the impact force applied externally to the housing. In a method for simulating the impact forces applied to glass bottles as they are conveyed in a bottling operation impact forces are applied at any angle to the housing and are transmitted to the accelerometer. The accelerometer is actuated to generate an output signal expressed in terms of the X and Y vectors of the impact force to the electrical circuitry. The output signal is processed to indicate the magnitude of the applied impact force.

A method for manufacturing a disk drive head suspension having a plated load point dimple. A photoresist mask having an opening with load point-defining side walls and a load point diameter is formed over a planar portion of a spring metal member. Metal is plated onto the spring metal member in the opening to form a load point having the load point diameter on the planar portion of the spring metal member.

A method for adjusting a performance parameter of a head suspension for positioning a read/write head in a disk drive. The suspension includes a beam and flexible element for carrying a read/write head extending from the beam. The flexible element has one or more adjustment portions. The beam has one or more openings adjacent to the adjustment portions of the flexible element to provide access to the adjustment portions through the beam. The method comprises acting upon one or more adjustment portions of the flexible element through one or more of the openings in the beam to change a performance parameter of the head suspension. A laser beam is used to irradiate the adjustment portions of the flexible element in one embodiment of the invention.
摘要:
A head suspension for a reverse flow disk drive. The head suspension includes a load beam having a mounting region at a proximal end, a rigid region at a distal end and a spring region between the mounting region and the rigid region. A flexure is mounted on the distal end of the rigid region. A slider is mounted on the flexure. The slider has a proximal end closest to the proximal end of the load beam, wherein the spring region, the rigid region, the flexure and the slider comprise an active portion. One or more read/write heads are located on the proximal end of the slider. A plurality of electrical traces extend along the head suspension to the proximal end of the slider. At least one airflow attenuator is provided that creates a region of reduced airflow velocity proximate at least a portion of the active portion. An actuator assembly and to a reverse flow disk drive are also disclosed.
摘要:
A head suspension assembly for a rigid disk drive. The head suspension has a load beam with a mounting region at a proximal end, a rigid region at a distal end and a tether connecting the mounting region and the rigid region. A hinge structure is located between the rigid region and the mounting region. The hinge structure comprises an interface with first pivot surfaces on the mounting region positively engaged with second pivot surfaces on the rigid region by the tether. A torsional spring is located between the rigid region and the mounting region.

A head suspension for supporting a head slider over a disk surface within a rigid disk drive includes a load beam with a flexure at a distal end of the load beam. The head suspension includes a motion limiter for restricting the range of motion of the flexure relative to the load beam. Toward this end, the motion limiter of the present invention includes a hook formed by bending a cantilever arm of the flexure to position a hook tip of the hook substantially over a load point of the suspension. The motion limiter constrains the load beam between the hook tip and the flexure in order to limit vertical displacement of the flexure relative to the load beam, as can occur through deflections caused by a shock load, through excessive pitch and roll motion of the flexure, or through operational movement of the head suspension assembly within the disk drive. The point contact of the hook tip substantially at the load point of the head suspension results in maximum gimbal freedom and minimum twist and distortion due to motion of the flexure. The motion limiter of the present invention is formed after a precursor structure of the load beam and co-planar flexure is formed, thereby eliminating the need for interleaving of the flexure with the load beam to achieve the desired hook positioning.
