摘要： A head support mechanism includes a slider equipped with a magnetic head to read/write information from/to a magnetic disk, a load beam to provide the slider with an appropriate load, the load beam being flexible in a direction substantially perpendicular to the disk, and a microactuator mounting portion equipped with a microactuator. A first actuator fixing portion, which connects the microactuator mounting portion to a carriage, and a second actuator fixing portion on the magnetic head side of the microactuator mounting portion, which connects the microactuator mounting portion to the load beam, are coupled by two arm portions of the microactuator mounting portion. The microactuator is mounted on the microactuator mounting portion so that the microactuator does not come into contact with the microactuator mounting portion between the first actuator fixing portion and the second actuator fixing portion.

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.
