Abstract:
A disk drive comprising:(a) an actuator arm; (b) a head coupled to the actuator arm; and (c) a voice coil motor for actuating the actuator arm to move the head, the voice coil motor comprising: a first magnet for generating a first magnetic flux; a yoke comprising a magnetic flux conductor for guiding the first magnetic flux, wherein: the magnetic flux conductor comprising at least one side portion and a first and second plate portions protruding from the side portion; the side portion and the plate portions being integrally formed; the first plate portion being spaced-apart from the second plate portion defining a gap between the first plate portion and second plate portion; and the side portion comprising a plurality of bends defining an interior bend path along an interior surface of the side portion coincident with the gap, the interior bend path traversing more than 180 degrees; and a voice coil for conducting a current to generate a second magnetic flux for interacting at least partially with the first magnetic flux.
