Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] A self-destructing hard disk, comprising a hard disk, a thermal degaussing self-destructing device 3, a destroy button 1, a lead wire 5 and a detonator 4; the thermal degaussing self-destructing device 3 is fixed to the inner surface of the idle space in the hard disk cover 2 with screws, and the hard disk, thermal degaussing Both the self-destruct device 3 and the detonator 4 are encapsulated in the casing; and the entire hard disk body is sealed with a sealant; the destruction button 1 is "concave" embedded in the casing, and the two ends of the lead wire 5 are respectively connected to the destruction button 1 and the detonator. 4 Fixed connection; the shell material is aluminum alloy, and the hard disk interface is IDE / ATA. The destroy button is activated, the battery provides energy, the detonator 4 detonates the thermal degaussing ...

Abstract

The invention discloses a self-destructive hard disk, which comprises a hard disk, a thermal-demagnetizing self-destructor (3), a destruction button (1), a lead wire (5) and a blast trigger (4). The inner surface of the inner unused space of the thermal-demagnetizing self-destructor (3) and a hard disk cover (2) is fixed by a screw, the hard disk, the thermal-demagnetizing self-destructor (3) and the blast trigger (4) are all encapsulated inside a shell, the whole hard disk body is sealed up by a sealing gum, the destruction button (1) is embedded in the shell in a concave way, both ends of the lead wire are fixedly connected with the destruction button (1) and the blast trigger (4) respectively and the shell is of aluminum alloy. When the destruction button is started, a battery provides energy, the blast trigger (4) triggers the thermal-demagnetizing self-destructor (3), and the surface temperature of the hard disk is instantly increased, causing the magnetic properties of hundreds of magnetic particles to be canceled out one another and showed no external magnetic property entirely and causing the whole magnetic dielectric layer to be a paramagnetic body, thereby the data on the magnetic dielectric layer is thoroughly destroyed. The invention can meet the requirement of destroying data rapidly, safely and thoroughly in emergency situations.

Description

technical field [0001] The invention relates to a method for destroying data on a hard disk for a computer, in particular to a method for physically destroying data on a hard disk for a computer. Background technique [0002] Currently, there are mainly two methods for destroying data on hard disks used in computers: physical destruction and logical destruction. Physical destruction refers to the destruction of hard disk platters, mainly by means of degaussing, chemical corrosion, and physical destruction. Logical destruction refers to the use of software to overwrite the hard disk multiple times. [0003] Degaussing is the use of a strong magnetic field to destroy the magnetic medium layer on the hard disk, usually using permanent magnets or coils; chemical corrosion is the use of chemical reagents sprayed on the disk to corrode the disk to destroy data; physical damage refers to scratches Disc, hard disk reheating, external damage (hammering, bullet shooting), etc. [00...
