Abstract
The invention discloses a design method of an HDD (Hard Disk Drive) capable of being quickly destroyed. The design method comprises the following steps: firstly, improving a magnetic read-write head to cause the magnetic read-write head to bear the circulation of large-power alternating current to generate a powerful electromagnetic field, wherein the electromagnetic field is powerful enough to destroy the data of a plurality of magnetic tracks to tens of magnetic tracks; when a data destroying instruction is not received, the HDD works under a normal mode so as to carry out a data read-write operation; when the data destroying instruction is received, the magnetic head of the HDD is immediately connected with a destroying circuit and generates the powerful electromagnetic field; at the time, the magnetic head arm of the HDD gradually inwards moves from the edge of a disk within few seconds; and at the same time, the disk operates at a high speed, and the powerful electromagnetic field of the magnetic head sweeps the whole disk in few seconds to destroy the data of the whole HDD. Compared with a situation that the traditional HDD destroys the data in an erasing way, the design method has qualitative leap and can improve a plurality of orders of magnitudes on an aspect of an erasing rate.
Description
Technical field
The present invention relates to hardware destroy technical field, specifically a kind of method for designing can destroying HDD hard disk fast.
Background technology
HDD hard disk, the abbreviation of Hard Disk Drive, i.e. hard disk drive.
Current, data security is more and more taken seriously, in recent years, the event that hard disk information is divulged a secret also emerges in an endless stream, therefore, hardware destroy technology becomes the especially military active demand of individual and enterprise, present hardware destroy technology is general and various, for HDD hard disk, due to the special construction of traditional HDD hard disk, when mechanical hard disk write data, major part data are continuous print, therefore data thoroughly to be destroyed, irrecoverable, only have and these data are all override, namely destroy data in the mode of low-level format, full format turns to " 0 " or " 1 ", this kind of mode is safe and reliable, otherwise, data will be reduced easily, but for the HDD hard disk of larger capacity, data are override completely, and data are all wiped, by the time of at substantial, this is when some are urgent, this time is just too very long, this is not allowed to, therefore, it is possible to the reliable HDD hard disk destroyed fast becomes a kind of demand in emergency circumstances.
Disclosed patent application document: number of patent application is " CN201010595945.4 ".Name is called " destroy device of hard disk, CD and semiconductor storage body "; this document disclose that " destroy device of a kind of hard disk, CD and semiconductor storage body, it is destroyed mechanism, discharging mechanism, power source feeding mechanism by feed mechanism, pressure, automatically to be controlled and safety guard etc. forms.Adopt the destroy device of the hard disk of said structure, CD and semiconductor storage body, can destroy thoroughly overall device such as hard disk, CD and the semiconductor storage bodies put between pressure destruction mechanism's dynamic pressure head and static pressure head, reach the requirement that classified document is destroyed.This equipment can make concerning security matters personnel can in person destroy above-mentioned confidential document and carrier thereof whenever and wherever possible, and that avoids the contact of unrelated person to cause divulges a secret.This equipment have easy to use, safe and reliable, be easy to the features such as maintenance.The operation of equipment to environment also without any harm ".
Number of patent application is " CN201410819023.5 ".Name is called " method of the irreversible self-destruction of a kind of solid state hard disc Long-distance Control power down preventing ", this document disclose " method of the irreversible self-destruction of a kind of solid state hard disc Long-distance Control power down preventing; the method step is as follows: under normal operating conditions; solid state hard disc normally works, carries out storage by the SSD controller NANDFLASH controlled in external data and solid state hard disc and transmits; When needs perform solid state hard disc self-destruction, send self damaging order to the telecommunication control module on solid state hard disc by the mode of remote radio communication; Telecommunication control module sends destruction instruction to the self-destruction control module in solid state hard disc, and self-destruction control module performs self damaging order, realizes self-destruction to solid state hard disc; Afterwards, the self-destruction control module in solid state hard disc can feed back self-destruction status information, and remote control communication module feeds back self-destruction execution state information by telecommunication mode to control people again.The present invention controls solid state hard disc by telecommunication and performs self-destruction, avoids data maliciously to be altered, steal or leak under special, the harsh conditions such as without permission ".
Above-mentioned open file, although can destroy hard disk, the HDD hard disk for larger capacity is difficult to destroy fast at short notice, thus prevents data from maliciously being altered, steal or leaking.
summary of the invention
Technical assignment of the present invention is to provide a kind of method for designing can destroying HDD hard disk fast.
Technical assignment of the present invention realizes in the following manner, and the method step of this destruction HDD hard disk is as follows:
First improve read-write head, make read-write head can the circulation of the high-power exchange current of load, to produce a powerful electromagnetic field, by force even as big as destroying the data of several magnetic track to dozens of magnetic track; When not receiving data destroying instruction, HDD hard disk operational, at normal mode, carries out the read-write operation of data; After receiving data destroying instruction, HDD hard disc magnetic head connects destruction circuit at once, and produce a high-intensity magnetic field, now, the head arm of HDD hard disk progressively internally moves from peripheral of disc within a few second, meanwhile, disc is running up, within a few second, the high-intensity magnetic field of magnetic head, by inswept whole disc, destroys the data of whole HDD hard disk.
Described read-write head is controlled by hard disk controller.
When described hard disk controller receives the order of data destroying, hard disk controller first disconnects head data read/write circuit, then connects data destroying circuit.
A kind of method for designing can destroying HDD hard disk fast of the present invention compared to the prior art, have reasonable in design, operate the features such as quick and convenient, data are destroyed in the mode of erasing compared to traditional HDD hard disk, be have qualitative leap, especially in erasing speed, several order of magnitude can be promoted, effectively prevent data from maliciously being altered, steal or leaking.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of FB(flow block) can destroying the method for designing of HDD hard disk fast.
