摘要： Embodiments of the present invention help to suppress performance degradation in an actuator of a disk drive device when attaching a damping member to a single surface of an arm. According to one embodiment, in a HDD a damping member is attached to a single surface of an arm. A shape of an inner arm is asymmetric with the center position between disks. Specifically, the thickness from a center position between the disks to the damping material attaching surface is thinner than the thickness from a center position between the disks to an opposite surface of the damping member attaching surface. This suppresses deformation of the vibration mode in the case that the damping member is attached to the single surface of the arm.

摘要： A head support mechanism includes a head to write/read information, and a head support member to support the head. The head support member has parts delimiting an opening at a portion thereof in which opposing parts which delimit the opening in a width direction of the head support member are elastically deformable. Protrusions are formed on edges of the opening, and piezoelectric elements are mounted on the protrusions to enable deforming of the head support member in a direction of positioning of the head.

摘要： A magnetic disk device having a head integrated circuit mounted on a magnetic head supporting mechanism. In order to secure the reliability by controlling the integrated circuit temperature below a predetermined level, the difference in the integrated circuit cooling ability which varies with the radial position on the disk is quantified, so that power (signal) sufficient to maintain a constant temperature according to the integrated circuit temperature is supplied to the integrated circuit. Since the cooling ability at a given radial position of the integrated circuit is not exceeded by the power consumption, the integrated circuit temperature can be maintained below a predetermined level.

摘要： In the magnetic disk unit comprising suspensions in each of which an IC is mounted on a load beam, a magnetic head displacement caused by the warp of the load beam occurring due to heat generated from the IC is compensated, whereby the shortening of an access speed and high reliability of reading/writing are realized. The thermal displacement of the magnetic head is compensated by operating micro actuators on the load beam in accordance with the temperature rise of the IC which is measured by a temperature sensor. Namely, by driving the micro actuators so that the magnetic head may move in a direction reverse to the direction of the magnetic head movement caused by the thermal displacement, the thermal displacement of the magnetic head is made to be substantially zero.
