    摘要: A process for producing a thin film magnetic head uses the upper magnetic pole as a self-aligning mask for partially trimming the lower magnetic pole, wherein the yoke and pole tip regions to be trimmed are processed by separate and distinct photolithographic steps, thereby achieving noncritical alignment in the yoke area, while maintaining critical alignment in the pole tip region which includes the transducing gap.

    摘要: Techniques and structures for providing flexibility of a micromachined transducer array. In an embodiment, a transducer array includes a plurality of transducer elements each comprising a piezoelectric element and one or more electrodes disposed in or on a support layer. The support layer is bonded to a flexible layer including a polymer material, wherein flexibility of the transducer array results in part from a total thickness of a flexible layer. In another embodiment, flexibility of the transducer array results in part from one or more flexural structures formed therein.

    摘要: A magnetic recording transducer for use in a data storage device includes a writer pole with a ABS surface, trailing edge bevel and a trailing shield. The effective throat height of the writer main pole is reduced by the use two gap layers between the writer main pole and the trailing shield. A first gap layer is on and in contact with the writer pole trailing surface, and a second gap layer is on a section of the first gap layer on the writer pole trailing edge bevel, from a point removed from the ABS surface and absent from a part on a section of the first gap layer on the writer pole trailing edge bevel nearest the ABS. A method of fabricating the transducer is also provided.

    摘要: A method and system provide a magnetic transducer having an air-bearing surface (ABS). The magnetic transducer includes a write pole and at least one coil. The write pole has a pole tip and a yoke. The coil(s) energize the write pole. The coil(s) include a plurality of turns a first distance from the pole and at least one additional turn a second distance from the pole. The first distance is different from the second distance. The at least one additional turn extends over at least part of two of the plurality of turns, has a length in a stripe height direction perpendicular to the ABS and has a height in a down track direction. The length is greater than the height.

    摘要: Optical components may be precisely positioned in three dimensions with respect to one another. A bonder which has the ability to precisely position the components in two dimensions can be utilized. The components may be equipped with contacts at different heights so that as the components come together in a third dimension, their relative positions can be sensed. This information may be fed back to the bonder to control the precise alignment in the third dimension.
