摘要： An improved microactuator magnetic circuit having a simplified assembly, reduced field leakage, and improved passivation methods is disclosed. To simplify assembly, a single magnet is polarized in two magnetic regions so that the single magnet is functionally similar to two separate magnets. In addition, the magnetic circuit can be produced without a top keeper. Field leakage is reduced by expanding the bottom keeper. Finally, corrosion-resistant alloys with acceptable magnetic properties are used in forming the keeper.

摘要： A method for fabricating an integrated coil-on-keeper assembly for use in a magnetic circuit to actuate a microactuator. The assembly is formed on a keeper substrate by patterning an insulator layer, plating at least one coil layer and patterning another insulator layer on top of each coil layer. The keeper substrate is etched to form the top keeper of the coil-on-keeper assembly.

摘要： A microactuation system selectively alters a position of a transducing head carried by a slider in a disc drive system with respect to a track of a rotatable disk having a plurality of concentric tracks. The microactuation system includes a head suspension having a first portion and a flexure for supporting the slider. A flexible beam extends from the first portion of the head suspension at one end to the flexure at the other end. An electroactive element is attached to the beam. The electroactive element bends in response to a control signal applied thereto. The beam is sufficiently compliant to permit movement of the first portion of the head suspension with respect to the flexure.

摘要： A microactuator finely positions a transducing head carried by a slider adjacent a select radial track of disc. A frame of the microactuator includes a motor for altering the position of the slider and a closed bonding tub extending upward from the bottom of the microactuator having a bonding surface to engage the top surface of the slider. The closed bonding tub is formed from the microactuator frame such that there is a tub bottom having a bonding surface, sidewalls and an open sidewall.

摘要： A slider having a slider body is provided for actively controlling a fly height of the slider relative to a data storage disc. A first plurality of beams are affixed to a back surface of the slider body. The beams are disassociated from one another and are constructed of deformable material. Each beam, in response to an applied electrical control signal is deformable in a first dimension parallel to the back surface of the slider body. Deformation of the first plurality of beams in response to an applied electrical control signal affects slider fly height by changing one of slider body crown and cross curvatures to a greater extent than along the other. In accordance with other embodiments, multiple layers of deformable beams are attached to a slider. In yet other embodiments, piezoelectric material layers having anisotropic properties are substituted for beam layers.

摘要： To allow for adjusting the fly height of a read/write head carried by a slider, a shear transducer is added to the slider. The shear transducer comprises a layer of piezoelectric material added to the slider so that the portion of the slider carrying the read/write head can be moved when the shear transducer is sheared. To cause the shear transducer to shear, a voltage is applied across the piezoelectric layer. To control the movement of the transducer, a closed-loop control system is used. The control system senses the spacing between the read/write head and the disc surface, compares the sensed spacing to a desired spacing, and adjusts the voltage applied to the shear transducer to reduce the difference between the actual and desired spacing.
