摘要： Embodiments of the invention appropriately control the flying height of a magnetic head slider as necessary without making the magnetic head slider touch the magnetic disk. In one embodiment, when a magnetic disk drive is started, the level of electric power predefined for the ordinary temperature (room temperature) is read in from the internal memory of an MPU. A temperature sensor measures the internal temperature of the magnetic disk drive and sends it to the MPU. According to the temperature sent from the temperature sensor, the MPU calculates the level of electric power which should be applied to a flying height adjustment structure. According to the calculated electric power, the MPU increases or decreases the electric power applied to the flying height adjustment structure. At a flying height controlled (corrected) by the flying height adjustment structure, a magnetic head slider performs read/write on a magnetic disk.
