Abstract: A suspension is provided with a base plate, load beam, and flexure. The base plate includes a boss portion, a first region situated on a side closer to a slider with respect to a center of the boss portion, and a second region situated on a side more remote from the slider. A pair of first projections are formed in the first region. A pair of second projections are formed in the second region. The projections project in the thickness direction of the base plate. The boss portion is inserted into a hole in an actuator arm, and the projections contact a suspension support portion of the actuator arm. The boss portion is pressurized from inside to be enlarged, whereby the base plate is fixed to the inner peripheral surface of the hole of the actuator arm.

Abstract: A head suspension 31 has a piezoelectric element 13 that deforms in response to a voltage applied thereto, a base plate 33 having an opening 43 into which the piezoelectric element 13 is fitted, and a load beam 35 that is fixed to the base plate 33 so that a front end of the load beam 35 moves in a sway direction according to the deformation of the piezoelectric element 13. The head suspension 31 includes an electric insulating layer 51 formed at the opening 43 by vapor-depositing and polymerizing electrically insulative high polymer materials at the opening 43. The piezoelectric element 13 is fitted into the opening 43 through at least the electric insulating layer 51. The head suspension 31 satisfies a miniaturization requirement.

Abstract: A control apparatus which generates control information on the basis of control target information from a control target, controls the control target by using the generated control information, and transmits the control information to an off-system control apparatus, includes a single common memory which stores both the control target information from the control target, and the transmitted control information.

Abstract: A slider tester includes a disk, movable table, table drive mechanism, guide member, etc. A plurality of suspensions are mounted on the movable table. A slider is mounted on each suspension. A guide member can support respective lift tabs of the suspensions. The guide member includes a first guide surface, second guide surface, and opening arranged in a track width direction of the disk. When any of the lift tabs gets into the opening as the movable table moves in the track width direction of the disk, the slider is dropped toward a recording surface of the disk.
