ABSTRACT:
A voice coil motor for a disk drive comprising a voice coil motor for driving an actuator, the voice coil motor including a coil (103) which has a first group of three sides (104, 105 and 108) that are located to be parallel with the rotation plane of the actuator, so as to traverse a vertical magnetic field formed by the voice coil motor; and a second group of three sides (106, 107 and 109) that are located to be perpendicular to the rotation plane of the actuator, so as to traverse a horizontal magnetic field formed by the voice coil motor.
Preferably, a pair of parallel sides (104, 105) of the first group of three sides and another pair of parallel sides (106, 107) are connected to each other at approximately right angles, respectively.
