摘要： A head gimbal assembly may include a piezo layer mechanically coupled with the slider. Bending the piezo layer alters flying height. Alternatively, it may include a piezo element mechanically coupled by a flexure to the slider top near the read-write head, which when excited, bends the flexure to alter the flying height. A bridge flex circuit is included, providing a piezo-control bundle to at least one of the piezo layer leads. The flex circuit assembly may further provide a piezo control bundle, shared with the piezo control bundles for multiple read-write heads. The head gimbal assembly may include a micro-actuator to position the read-write head near a track on the accessed, rotating disk surface. The flex circuit assembly may provide a source control bundle, shared with micro-actuator control bundles for multiple read-write heads. When accessing, all micro-actuators perform the same positioning action, insuring proper positioning of the read-write head. This applies to co-located and non co-located micro-actuators. Wire bundles may include one or two active signal wires. Voice coil actuators and the hard disk drives, as well as making these, are included.

摘要： The invention includes a D33 mode piezoelectric actuator region, including electrodes of differing length to produce a bending motion. The invention also includes a piezoelectric actuator containing a first piezoelectric actuator region coupled to a second piezoelectric actuator region, which may be separated by the ceramic material. Applying a first potential difference between electrodes generates a first bending of the piezoelectric actuator region. Applying the negative first potential difference generates the complement first bending for the piezoelectric actuator. The piezoelectric actuator region may be used to radially move a coupled transducer by the first bending. The piezoelectric actuator may be used to radially move a coupled transducer by the first bending and/or its complement. The invention includes the methods of making the piezoelectric actuator region and the piezoelectric actuator, and their products.
