System, method, and apparatus for flexure-integrated microactuator for magnetic heads

A piezo in-tongue microactuator includes a suspension assembly with a flexure tongue. The tongue has two slots that accept piezo actuators. The tongue also has multiple hinge flexible elements that translate the extension and/or contraction of the piezo actuators into rotary motion of the recording...

Summary:A piezo in-tongue microactuator includes a suspension assembly with a flexure tongue. The tongue has two slots that accept piezo actuators. The tongue also has multiple hinge flexible elements that translate the extension and/or contraction of the piezo actuators into rotary motion of the recording head. This rotary motion is then used to precisely position the recording element over the desired track on the hard disk drive and permits higher track density to be achieved.
