Abstract

See full text

A magnetic disk device includes a swing-type head actuator which is driven by a voice coil motor. The voice coil motor is cooled by an airflow generated when a magnetic disk accommodated in a disk accommodating unit of an enclosure is rotated by a spindle motor. An airflow dividing member provided on an inner wall or a base of an actuator accommodating unit divides the airflow generated by the rotation of the disk and passing along the inner wall. The divided airflow is introduced to a coil part of the voice coil motor, and cools the coil, without sacrificing the dust purge performance.
