Diskette Hard Disk Data Self

Diskette Hard Disk Data Self-

We know the diskette hard disk can be used to store data, but there is no good way to destroy the data thoroughly. But there is significant risk of leasing data if we just discard the hard disk drive when it will not in use. Nowadays there are three ways to handle it but with strong limitation.


1. Delete it directly. But it's very easy to restore back by software method

2. Use some non-useful data to overwrite it. But it's very slow, and still can be restored back; the effect for different diskette is quite different.

3. Destroy the diskette physically. But there must be professional machine and people to manipulate, and cannot be destroyed timely.

In this invention, a mechanical device to destroy the magnetic paintcoat on the diskette is added inside of the hard disk. When necessary it will destroy the magnetic paintcoat timely and thoroughly.

Diskette hard disk uses its magnetic head to detector change the magnetic property of a point on the diskette so as to read or write data in itself. If the magnetic paintcoat can be destroyed thoroughly, the data stored can also be destroyed forever.

Our invention is to add a mechanical arm (see Figure-1) inside of the diskette hard disk. When the disk is in use to store data, the mechanical arm will stay away from the magnetic diskette; when the disk needs to destroyed, the arm will move over it and start to destroy it. Of course the mechanical arm needs to arm w...
