摘要： A head assembly having a sensor element on the head assembly. Embodiments of the sensor element are configured to detect non-contact induced head-media interface instability, “onset of contact” or low level interference. The non-contact head-media instability or interference is detected based upon sensor feedback relating to excitation of the air bearing resonance modes of the slider body. In embodiments of the present invention, the sensor head assembly includes a microactuator which is energizable to microactuate the head or transducer elements on the head assembly.

摘要： A system for poling piezoelectric devices comprises a plurality of thin-film components, a plurality of piezoelectric devices, a poling pad for poling the piezoelectric devices, a plurality of traces, and a plurality of current-limiting elements. The thin-film components are separated by dice lanes to form an array, and the piezoelectric devices are formed on the thin-film components. The traces connect the piezoelectric devices across the dice lanes in parallel to the poling pad. Each current-limiting element is connected in series with one of the piezoelectric devices, in order to limit current to individual piezoelectric devices that experience current-related failure.

摘要： An improved microactuator suspension is provided for use with high density storage media. The number of microactuator elements is reduced to one and placed perpendicularly to the longitudinal axis of the suspension arm to maximize the windage and resonance performance and minimize the microactuator's contribution to bending stiffness and the off track bending component. An improved electrical connection eliminates the requirement for a jumper. These improvements reduce cost by reducing part count and assembly complexity.

摘要： A disc testing system includes a base, a disc rotatably attached to the base, and an actuator assembly movably attached to the base. A ramp assembly includes a set of ramps for loading and unloading the sliders and transducing elements carried by the sliders to and from the disc attached to the base. A load spring is attached to the arm of the actuator. A slider is attached to the load spring. The slider further includes a leading edge and a trailing edge. A piezoelectric sensor and a pyroelectric sensor is carried by the trailing edge of the slider. The piezoelectric sensor and the pyroelectric sensor are made from the same material which has both piezoelectric properties and pyroelectric properties. The piezoelectric sensor and the pyroelectric sensor are formed by the same process. The two sensors can also be formed substantially simultaneously. A conductive layer is placed on the trailing edge of the slider followed by a strip of thick film material. Epoxy may be added to the sensors to form a composite of epoxy and lead titanate zirconate.
