Disk drive with air-flow control component

摘要

A disk drive. The disk drive includes a motor, a base to which the motor is affixed, an actuator supporting a head-slider, and an air-flow control component affixed inside the base. The motor is configured to spin a disk. The actuator is configured to access the disk and to rotate about a pivot shaft to move the head-slider. The air-flow control component includes a plate which faces a recording surface of the disk, and a support portion supporting the plate. The thickness of the plate gradually decreases towards an outflow side of the air-flow control component. The bodies of the plate and the support portion are made of resin; and, a surface of the plate is configured to be held at an electrical potential selected from the group consisting of ground potential and a negative potential.
