Hard disk drive having air flow accelerating device

摘要

A hard disk drive having an air flow accelerator for improving taking-off and landing of a slider on a surface of a disk. The hard disk drive includes a spindle motor and a disk for storing data which is rotated by the spindle motor. The slider includes a magnetic head for recording and reproducing data and is mounted on a pivotable actuator. The air flow accelerator is provided within an inner circumference of the disk and rotates together with the disk. The device may be formed integral with a disk clamp, the spindle motor, a disk spacer, the disk, or as a separate member. At least one blade extends in a radial direction from a center of rotation of the disk with the blade being curved in a direction opposite a rotation direction of the disk. The accelerated air flow restricts damage of the magnetic head and the disk.
