Data erasing apparatus
View Patent ↗The invention enables a magnetic disk drive to be inserted and removed against an attraction force exerted by a magnetic force that is strong enough to erase data on a magnetic disk enclosed within a metal case. A converting mechanism comprising a ballscrew and a ballscrew nut bracket is provided that converts rotational motion of a handle into translational motion of an HDD holder; by rotating the handle, the HDD holder with the hard disk drive mounted thereon is moved in the inserting and removing directions by overcoming the attraction force being exerted by the magnetic field generated by means of a permanent magnet. An electric motor may be used to generate the rotational force.
1. A data erasing apparatus for erasing data recorded on a magnetic disk contained in a magnetic disk drive, comprising:
magnetic field generating means, having a space capable of accommodating the entire magnetic disk drive, for applying a magnetic field by means of a permanent magnet to the magnetic disk contained in the magnetic disk drive accommodated in the space; and
a moving mechanism for moving the magnetic disk drive, in inserting and removing directions, in the space of the magnetic field generating means by overcoming an attraction force exerted by the magnetic field, wherein the moving mechanism moves the magnetic disk, contained in the magnetic disk drive, at a translational motion along the space of the magnetic field generating means for erasing the data recorded on the magnetic disk.
2. A data erasing apparatus according to claim 1 , wherein the moving mechanism includes a converting mechanism for converting rotational motion into translational motion, thereby making possible the movement overcoming the attraction force.
3. A data erasing apparatus according to claim 2 , wherein the moving mechanism includes a rotatable handle for giving a rotational force to the converting mechanism.
4. A data erasing apparatus according to claim 2 , wherein the moving mechanism includes an electric motor for giving a rotational force to the converting mechanism.
