    摘要： A magnetic disk apparatus includes a magnetic disk on which information is stored, a magnetic head which performs writing-in and reading-out of information, a suspension which supports the magnetic head, and a suspension supporting member having a φ-shaped hinge. The suspension is supported at a tip end of the φ-shaped hinge and an actuator for moving the magnetic head to a predetermined position on the magnetic disk is disposed so as to bridge an open portion of the φ-shaped hinge. The actuator is coated with a resin material.

    摘要： Provided is a magnetic disc apparatus comprising a magnetic head for writing and reading data to and from a magnetic disc, a slider for floating up the magnetic head from the magnetic disc on rotation, a suspension having an IC chip mounting surface, for supporting the slider, a positioning mechanism for positioning a magnetic head at a predetermined position, and an IC chip mounted on the IC chip supporting surface of the suspension, wherein the rate of variation in temperature difference between opposite sides of the IC chip mounting position as a center on the IC chip mounting surface is set to be below about 3.5 K/sec. Thereby it is possible to restrain the averaged seek time for the magnetic disc from becoming longer.

    摘要： An actuator of a magnetic disk has a laminated construction of piezoelectric flat sheet in which there are two polarized regions separated by a non-polarized region and the polarization direction and the direction of applied magnetic fields are the same as the thickness direction of the piezoelectric flat sheet. The actuator is fixed in such a manner as to bridge the top surfaces of the suspension and suspension-supporting member of the magnetic disk, and is coated with a resin material. The actuator enables vertical vibrations and dust generation which occur in association with the movement of the supporting member to be reduced and the accuracy of head positioning to be improved.
