    摘要： A micro-actuator is comprised of a piezoelectric motor mounted on a flexure tongue with offsetting hinges, to perform a fine positioning of the magnetic read/write head. The substantial gain in the frequency response greatly improves the performance and accuracy of the track-follow control for fine positioning. The simplicity of the enhanced micro-actuator design results in a manufacturing efficiency that enables a high-volume, low-cost production. The micro-actuator is interposed between a flexure tongue and a slider to perform an active control of the fly height of the magnetic read/write head. The induced slider crown and camber are used to compensate for thermal expansion of the magnetic read/write head, which causes the slider to be displaced at an unintended fly height position relative to the surface of the magnetic recording disk. The enhanced micro-actuator design results in reduced altitude sensitivity, ABS tolerances, and reduced stiction. The controlled fly height of the magnetic read/write head prevents a possibility of a head crash, while improving the performance and data integrity.

    摘要： A head gimbal assembly includes a slider and novel gimbal that may reduce crown sensitivity to temperature without substantially sacrificing the ability of a bond between the gimbal tongue and slider to resist applied forces and torques. The gimbal has a tongue that includes at least one weakening region. The weakening region extends more in a direction perpendicular to the length of the slider than it does in a direction parallel to the length of the slider. A bonding surface of the slider is attached to the tongue in a first bonding region that extends closer to a leading end of the slider than the weakening region does, and in a second bonding region that extends closer to a trailing end of the slider than the weakening region does. The gimbal can be used in a head gimbal assembly of a magnetic hard disk drive or other information storage device.

    摘要： An electrically conductive adhesive includes a resin component, a photoinitiator, and metal-coated polymer beads. The beads have an average diameter and a very narrow size distribution around the average diameter. The adhesive is applied between a read/write head and a suspension to attach the two, and the adhesive is cured by exposure to an illumination and/or heat. The beads in the adhesive can form a monolayer between the read/write head and the suspension such that a spacing therebetween is equal to the average diameter of the beads. The metal coating of the beads provide electrical conductivity between the read/write head and the suspension.

    摘要： An electrically conductive adhesive includes a resin component, a photoinitiator, and metal-coated polymer beads. The beads have an average diameter and a very narrow size distribution around the average diameter. The adhesive is applied between a read/write head and a suspension to attach the two, and the adhesive is cured by exposure to an illumination and/or heat. A pad spacer is included between the read/write head and the suspension to define a spacing and parallelism therebetween. The beads in the adhesive can form one or more layers between the read/write head and the suspension or can be disordered. The metal coating of the beads provide electrical conductivity between the read/write head and the suspension.
