<P>PROBLEM TO BE SOLVED: To prevent a collision against a disk due to thermal deformation of near-field light emission element, and keep a constant distance between a heat-assisted magnetic recording head and the disk. <P>SOLUTION: A heat-assisted magnetic recording device includes a control unit that obtains a deformation around a near-field light emission element 24 from a temperature sensor 26 for measuring a temperature around the near-field light emission element 24, a table in which a relation between the temperature around the near-field light emission element 24 and the deformation is recorded, the temperature measured by the temperature sensor, and the relation between the temperature and the deformation recorded in the table, and adjusts the distance between the heat-assisted magnetic recording head 2 and the disk 1 by driving a floating height adjusting actuator 27 based on the deformation, so as to avoid a contact thereof. <P>COPYRIGHT: (C)2012,JPO&INPIT |
