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： 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.
