摘要： Apparatus and method for light source power control during the writing of data to a storage medium. In accordance with various embodiments, a data recording head is provided having a magnetic transducer and a light source. The light source is driven at a first power level to irradiate an adjacent storage medium prior to the writing if data to the medium using the magnetic transducer. The first power level is insufficient to alter a magnetization state of the medium. The light source is subsequently transitioned to a higher, second power level to irradiate the storage medium during the writing of data to said medium using the magnetic transducer, the second power level being sufficient to alter said magnetization state of the medium.

摘要： A microactuator 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 microactuator design results in a manufacturing efficiency that enables a high-volume, low-cost production.

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 rotary microactuator-based head-gimbal assembly design controls the unwanted deflection of a flexure in a data storage device and eliminates hinge deformation. The head-gimbal assembly maintains the co-planarity of the hinged islands in the microactuator under the applied load acting on the flexure and two associated hinged islands. The dimple post is placed at the dimple loading region of the flexure tongue and has the same height as adhesive dams on paddles secured to the hinged islands. The dimple post is formed by branching one of the existing conductive traces covered by a photoresist layer to the dimple loading region on flexure tongue. In an alternative embodiment, the dimple post is secured to the dimple loading region of the flexure tongue by means of adhesives with a variety of viscosity and elastic moduli.

摘要： Devices are provided herein in a variety of examples that inhibit particle pickup and transport and mechanical vibrations and provide other advantages. In one illustrative example, an actuator assembly includes a base, an actuator disposed on the base, and a shroud disposed on the base around the actuator. The shroud includes one or more shroud walls disposed between the actuator and a flow channel exterior to the shroud. The shroud walls may include shielding walls that partially surround the actuator, radially curved shroud wall segments, fastener well shields that substantially separate an interior thereof from the actuator, and other aspects. A data storage device may have a flow path defined therein, and the shroud may be disposed around an actuator within the data storage device, providing a streamlined surface between the flow path and the actuator.
