摘要： A disk head fly height adjustment method includes positioning a disk head over a surface of a rotating data storage disk and dynamically altering a load point of the disk head by changing an electrical force applied to an active element mounted to a head-gimbal assembly. A data storage apparatus includes a head assembly having a data transfer head coupled to a gimbal and an active element coupling the head assembly and a suspension. The active element is configured to exert a force between the head assembly and the suspension in response to an electrical force applied to the active element. The active element can dynamically shift a load point of a disk head. Shifting the load point can alter the pitch of the disk head and, consequently, the fly height of the head.

摘要： A glide head apparatus for testing surface characteristics of a disc includes a gimbal, a slider and an actuator including a piezoelectric material disposed between the gimbal and the slider. A voltage applied across the piezoelectric material is controllable to cause the piezoelectric material to expand or contract depending on the applied voltage so as to vary the fly height between the slider and a disc under test. The fly height can be varied without substantially varying the linear velocity of the disc under test. Methods of testing surface characteristics of a disc using the glide head apparatus also are disclosed.

摘要： A method and system is disclosed for minimizing parasitic losses associated with a liquid crystal display (LCD) of a device. A frame buffer may be used in conjunction with a driver circuitry integrated circuit. The frame buffer may store a set of display values for the LCD so that the display values corresponding to a plurality of frames may be transmitted together from a processor in a burst. Once the values are transmitted, the processor may idle or hibernate. Alternatively, only the changes to an image may be transmitted from the processor to the driver circuitry. The remaining pixel values may be drawn based on values previously stored in the frame buffer. Furthermore, the driver circuitry may be used to step up the received display rate values to a level that allows for inversion of the polarity of pixels in the LCD using frame inversion.

摘要： An improved glide head has optical marks on the air bearing surface. The glide heads can be used for detecting defects on disc surfaces following an evaluation of the fly height as a function of disc rotation. The optical marks provide a position for focusing light used in the optical measurement of fly height. The optical marks have measurably different optical properties from the portions of the air bearing surface not covered by an optical mark. The differences in optical properties of the optical marks can be used to adjust the position of the optical system relative to the glide head to ensure that the light is focused on an optical mark.
