Actuator for use with a disk drive having a coil assembly including a bobbin to aid in heat convection from the coil of the coil assembly

摘要

Disclosed is an actuator for use with a disk drive having a coil assembly including a bobbin to aid in heat convection from the coil of the coil assembly. The actuator includes a body portion for pivotally coupling to the disk drive and an actuator arm cantilevered from the body portion for supporting a head gimbal assembly (HGA). The actuator further includes a coil assembly having a fork, a coil, and a bobbin. The fork is cantilevered from the body portion in an opposite direction from the actuator arm and includes a pair of opposed prongs to mount the coil and the bobbin therebetween. The bobbin includes at least two opposed fins to aid in the convection of heat from the coil.
