Problems solved by technology

[0003] However, this technical solution is to use the degaussing module to degauss the hard disk as a whole and then crush it. Because the overall size of the 3.5-inch standard hard disk is relatively large (146×101×26 mm)
Not only will the cross-sectional area of ​​the coil cavity be larger directly, but the volume and weight of the coil need to be increased, and after the coil cavity area is large, the capacity of the energy storage capacitor and the discharge voltage must be increased to ensure sufficient magnetic field strength, which increases the manufacturing cost
[0004] In addition to the above-mentioned degaussing equipment, there are some degaussing equipment whose operation method is to put the hard disk in the storage box, manually push the storage box into and out of the degaussing coil, and cannot degauss the hard disk continuously
