Abstract

The invention relates to a magnetic storage medium degaussing machine with improved performance. The machine comprises a charging circuit, a boost rectification current-limiting circuit connected withthe charging circuit, a degaussing coil connected with the boost rectification current-limiting circuit, and a microprocessor connected with the charging circuit and the degaussing coil. Wherein thecapacitor modules are connected with the boost rectification current-limiting circuit in parallel, and the capacitor voltage acquisition module and the capacitor overcharge protection module are connected with the capacitor modules in parallel. Circuits are reliable, and the magnetic field intensity can be increased only by adding the capacitor module under the condition that the original circuitdesign is not modified; and the product is high in universality, suitable for mass production and low in maintenance cost.

Description

technical field [0001] The invention relates to a magnetic storage medium degausser with improved performance. Background technique [0002] According to the data of the National Security Technology Testing Center, a total of 885 products have obtained the technical certification of the National Security Technology Testing Center, including 98 items in the secret sales and information erasure list. Among the 98 certifications are mainly media information erasure tools, media degaussers, media destroyers, paper shredders, media shredders, etc. Generally speaking, for magnetic storage media such as hard disks, floppy disks, and magnetic tapes, destruction equipment such as demagnetizers is generally used to destroy information, while for non-magnetic storage media such as CDs and U disks, destruction equipment such as shredders is mostly used for information destruction. Incineration equipment is generally rarely used in office environments because it requires a special workp...
