  • Method and system of using a step plate mechanically formed in a disk drive suspension flexure to mount a micro-actuator to the flexure
    Patent number: 7660079
    Abstract: A head gimbal assembly includes a suspension including a suspension flexure. The suspension flexure includes a step plate mechanically formed in the suspension flexure. A micro-actuator is mounted to the step plate of the suspension flexure. The step plate is constructed and arranged to support the micro-actuator such that a substantially constant gap is maintained between a top support of the micro-actuator and the suspension flexure in use.

  • Techniques for reducing flexure distortion and gimbal separation for thin-film PZT micro-actuators of head gimbal assemblies
    Publication number: 20080144225
    Abstract: Systems and methods for reducing flexure distortion and/or gimbal separation for thin-film piezoelectric transducer (PZT) micro-actuators for head gimbal assemblies (HGA) of disk drive devices are provided. In certain example embodiments, a head gimbal assembly may comprise a suspension including a suspension flexure. The suspension flexure may include a micro-actuator mounting region. A micro-actuator may be mounted to the micro-actuator mounting region of the suspension flexure. At least one support may be formed on the micro-actuator mounting region, such that the support increases the stiffness of the suspension flexure. The supports may be a single bar-shape, two separated bar-shapes, circle-shaped, rectangle-shaped, cross-shaped, etc. The supports may be made of metal, and they may be formed by chemical etching.
