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.
摘要翻译：头部万向架组件包括滑块和新颖的万向架，其可以降低冠部对温度的灵敏度，而基本上不会牺牲万向节舌片和滑块之间的接合以抵抗所施加的力和转矩的能力。万向节具有包括至少一个弱化区域的舌头。弱化区域在与滑块的长度方向垂直的方向上比在滑块的长度方向上延伸更多。滑块的接合表面在与弱化区域相比更靠近滑块的前端的第一接合区域中附接到舌部，并且在比第二接合区域更靠近滑块的后端的第二接合区域中弱化区域。万向节可用于磁盘驱动器或其他信息存储设备的磁头万向架组件中。

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.
