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.

摘要： Return channels 45a, 45b, 45c, and 50 are formed to guide air flowing through a clearance between a magnetic disk (11) and a shroud (41) so that the air flows behind a voice coil motor, bypasses a loading/unloading mechanism (31) and flows toward a region on the lower side of the loading/unloading mechanism 31 with respect to the rotating direction of the magnetic disk (11). Thus, production of turbulent flow in the vicinity of the loading/unloading mechanism 31 is controlled. Fluttering of the magnetic disk (11) can be controlled by placing a filter 60 in one of the return channels.

摘要： The magnetic head assembly including a magnetic head having a terminal composed of a conductive film and a supporting spring. The supporting spring has interconnecting patterns (lines) on the top thereof and a projective electrode. The terminal of the magnetic head is electrically connected to the projective electrode of the supporting spring by a solderless, direct contact connection. The magnetic head is fixed to the supporting spring by using a non-electrical bonding agent. This structure makes it possible to stabilize the position of the magnetic head assembly and the relative speed variation between the magnetic head element and the magnetic disk, thereby enhancing the reliability of the magnetic disk apparatus.
