The present invention provides a kind of technical solution referring to FIG. 1-2:
A kind of hard disk drive, disk 5 including hard disk shell 1 and containing magnetic recording layer and to the magnetic recording
Layer carries out the record and regenerated magnetic head 10 of magnetic data, and the disk 5 is mounted on the outside of wheel hub 6, the bottom of the wheel hub 6
It is fixedly installed with rotating vane 4,1 bottom surface of hard disk shell is fixedly installed with fixing seat 2, the top of the fixing seat 2
It is fixedly connected with inside bearing 3,3 outside of bearing is connect with the inside of rotating vane 4, outside the left end of the rotating vane 4
Portion is equipped with pressure fan 7.
Specifically, the wind passage mouth of the pressure fan 7 is corresponding with rotating vane 4；Convenient for the rotation band driving wheel of rotating vane 4
Hub 6, so that disk 5 quickly rotates.
Specifically, the disk 5 is to stack gradually magnetic recording layer, protective layer and lubricating film on aluminum base plate and make
Make；Aluminum base plate can also be replaced and use glass substrate.Magnetic recording layer is the magnetic substance by sputtering stacking Co, Pt etc.
And formed.Protective layer is formed by sputtering stacking diamond-like carbon film etc.；The protective layer is in magnetic head 10 and high speed rotation
Disk 5 contact when, protect magnetic recording layer, protect it from damage.Lubricating film is formed by applying liquid organic matter.The profit
Synovial membrane, when magnetic head 10 and high-speed rotating disk 5 contact, lubricating magnetic head 10 exempts from it to protect magnetic head 10 and disk 5
It is damaged.
Specifically, the magnetic head 10 is mounted on the front end from the outside of disk 5 extended linking arm 9 inwardly, the company
The rear end and 8 output shaft of variable-frequency motor for connecing arm 9 are sequentially connected；MagneticThe record of property data is by flowing through in coil (not shown)
