摘要： A disk writing apparatus includes: a temperature sensor sensing an ambient temperature of a disk; a sync mark generator generating a sync mark having a pattern when a writing temperature indicating an ambient temperature at which data is written on the disk is sensed, wherein the pattern of the sync mark corresponds to the sensed writing temperature; a writing controller outputting the writing temperature sensed by the temperature sensor to the sync mark generator; a multiplexer adding the sync mark generated by the sync mark generator to the data; and a writing unit writing the data to which the sync mark is added on the disk. Accordingly, error rates when data is written and when data is reproduced can be improved by optimally compensating for the disk writing temperature and the disk reproducing temperature using parameters of devices of an hard disk drive.

摘要： An actuator of a hard disk drive includes a swing arm having an axis or rotation, a suspension extending from a distal end of the swing arm, a read/write head mounted on the suspension, a coil support fixed to a proximate end of the swing arm so as to rotate with the swing arm and to which a voice coil motor coil is wound, a respective magnet disposed above and/or below the voice coil motor coil as facing the voice coil motor coil, and at least one magnetic retracting member of a magnetic material fixed to the coil support and attracted to the magnet. Each magnetic retracting member arrives close to the magnet when the swing arm is rotated clockwise or counterclockwise about its axis of rotation. Thus, the force of attraction between the magnetic retracting member and the magnet biases the wing arm in one of its directions of rotation such as that in which the swing arm is moved during an unloading operation in which the read/write head is parked.
