Abstract
An actuator device of a hard disk drive for reducing a disturbance affecting an actuator. The actuator device has a guide unit connected or attached to an actuator arm for reducing a disturbance affecting the actuator, caused by an air flow generated from a surface of the disk during disk rotation. The guide unit maintains a laminar flow of air between the disk and the actuator arm as the disk is rotated by a spindle of the hard disk drive.
Claims20
A hard disk device comprising:
- a disk
- a spindle for rotating said disk at a predetermined speed;
- actuator means for positioned an actuator head over an object track of said disk;
- and
- guide means attached to said actuator means for guiding an air flow generated on a surface of said disk during rotation of said disk by said spindle into a substantially laminar flow.
2 more elements
A hard disk device comprising:
- a disk
- a spindle for rotating said disk at a predetermined speed;
- actuator means comprising:
- a head gimbal for supporting an actuator head;
- an actuator arm for supporting said head gimbal;
- and
- a voice coil motor for positioned said actuator head over an object track of said disk;
- and
- guide means attached to said actuator arm for guiding an air flow generated on a surface of said disk during rotation of said disk by said spindle into a laminar flow.
6 more elements
A method for controlling air flow between a disk and an actuator arm, said method comprising the steps of:
- forming a guide unit having a streamlined shape;
- positioned to travel above a flat surface of a disk interacting with an actuator head carried by said actuator arm to store digital data on the flat surface;
- attaching said guide unit to at least one side portion of said actuator arm;
- rotating a disk to generate an air flow for enabling a head to fly above said disk;
- guiding said air flow into a laminar flow of air by use of said guide unit.
