The invention relates to a storage medium office destruction machine with degaussing function, in particular to a novel storage device which integrates shredded paper, smashed optical disc, U disk and IC card, and demagnetizes the magnetic storage medium such as hard disk and magnetic tape. Media office destruction machine. At present, with the rapid development of electronic technology, there are more and more types of information storage media. It is becoming more and more common to use optical disks, I disks, floppy disks, hard disks, magnetic tapes such as video tapes, audio tapes, data stream tapes, 1C cards, magnetic cards, etc. to store data or data. When people want to destroy various data on the storage medium, there are two main ways: One is the traditional method of mechanical pulverization and destruction, that is, according to different materials of the information storage medium, the pulverization treatment is separately targeted. For example, a pulverizer is used to pulverize paper, an optical disk, a u disk, and a memory card, thereby achieving the purpose of confidentiality of information. Another method is physical destruction, that is, an electromagnetic field is used to generate an instantaneous strong magnetic field, so that the magnetic field strength of the magnetic field is greater than the magnetic coercive force of the magnetic storage medium placed in the device, and the electromagnetic destruction method is used for the hard disk. Processing is performed to achieve the purpose of destroying various information on the magnetic storage medium.
