Abstract

PROBLEM TO BE SOLVED: To instantaneously erase data when the magnetic information such as a floppy disk wherein important confidential data, etc., are stored, is annulled. SOLUTION: By arranging two permanent magnets of approximately 3,000 gauss so as to face each other keeping a space of 10 mm and making a medium such as a flexible disk to pass through this space, the magnetic information is instantaneously erased, and also the running cost of power source, etc., is suppressed.

Field of the Invention The present invention relates to an apparatus for instantly erasing magnetic information on a floppy disk or the like. Conventionally, in order to erase information recorded on a floppy disk or the like, it has been necessary to format the information with a machine (hardware such as a computer) on which the information is recorded. [0003] However, at present, it takes a long time to perform a format operation, and it takes about 30 to 60 seconds to replace a 3.5-inch floppy disk, and it takes time to replace the floppy disk. A problem to be solved is that when magnetic information such as a floppy disk storing important confidential data is discarded, the data is instantly erased. The most important feature of the present invention is to instantly erase data by using a permanent magnet and passing a floppy disk between magnets. DETAILED DESCRIPTION OF THE INVENTION A permanent magnet of about 3,000 gauss is used for 10 m.
We opened a space of m and faced each other, and by passing a floppy disk through that space, we were able to instantly erase magnetic information. FIG. 1 is a schematic view of the apparatus of the present invention. The permanent magnets attract each other at N pole and S pole. [0008] A space of about 10 mm is created between the permanent magnets. By passing a floppy disk through the space, magnetic information is instantly erased by the magnetic force of the permanent magnet. As described above, the magnetic information erasing apparatus of the present invention realizes instantaneous erasure of magnetic information without using running costs such as a power supply.
