摘要： A voice coil motor for a disk drive includes a permanent magnet, a voice coil adapted to move in an arc proximate to the permanent magnet, a top plate positioned above the voice coil, and a bottom plate positioned below the voice coil. The permanent magnet has two halves that are magnetized in opposite direction. The two halves of the magnet are split into a right half magnet portion and a left half magnet portion. The right half magnet portion and the left half magnet portion are attached to the top plate and the bottom plate respectively at opposite sides of the voice coil motor. The invention also discloses a disk drive unit with such VCM.

摘要： A voice coil motor for a hard disk drive includes an inner core having an inner surface, an outer plate having an inner surface, a permanent magnet, and a coil of wire. The outer plate is positioned in spaced relation to the inner core such that a gap is defined between the inner surfaces of the inner core and the outer plate. The permanent magnet is located in the gap and attached to the inner surface of the outer plate. The coil of wire wraps around the inner core to form a solenoid coil. With such structure, the stiffness of the coil is increased. The invention also discloses a disk drive with such VCM in which the coil is directly bonded to the E-block of the hard disk drive. Therefore heat conduction of the hard disk drive is improved.
