Abstract: A method and apparatus for controlling a rotation of a motor in a disk drive. The method includes: performing spin-up when the disk drive is operating and determining whether a disk rotation speed is less than predetermined target constant revolutions per minute (RPM); rotating a disk at predetermined low RPM when determining that the disk drive is at a low temperature and changing a rotation mode to a low-speed rotation mode if it is determined that the disk rotation speed is less than the predetermined target constant RPM; and spinning up the disk to the target constant RPM when determining that the temperature of the disk drive has increased and changing the rotation mode to a high-speed rotation mode if a disk rotation driving current decreases below a predetermined reference current value while the disk is rotating at the low RPM. Accordingly, since spin-up can be normally performed through a step-by-step spin-up process even if a disk drive operates at a very low temperature, a normal operation and reliability of the disk drive can be guaranteed, and an excessive driving current for the normal operation of the disk drive is not required at the very low temperature.

Abstract: A flexible printed circuit board has a flexible dynamic region, and relatively rigid static regions between which the dynamic region extends. Portions of a base layer, a patterned conductive layer extending on the base layer, and a cover layer covering the conductive layer make up the dynamic region. Extensions of the base layer, the conductive layer, and the cover layer, and portions of a metal layer to which the base layer is attached make up each of the static regions. The metal layer enhances the rigidity of the flexible printed circuit board at the static regions. The metal layer also has rounded corners at sides of each of the boundaries between the dynamic region and each of the static regions to minimize stress concentrations at the boundaries. The conductive layer is made up of real traces through which electrical signals are transmitted, and dummy traces. The dummy traces are disposed outwardly of the real traces to prevent the flexible printed circuit board from cracking at the boundaries between the dynamic region and each of the static regions. In an HDD, the flexible printed circuit board electrically connects a head stack assembly (HSA) and a main circuit board.

Abstract: 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.
