Description

Small data storage medium destroyer and its operation method

Technical field

The present invention relates to the field of small devices, and in particular to an apparatus and method for destroying a data storage, and more particularly to a small data storage medium destruction machine and a method for operating the same.

Background technique

It turns out that when the data stored in the data storage device is deleted, the data storage device is discarded. Some professionals can recover the original data after using these discarded data storage devices. If these data storage devices contain some confidential government information or some highly sensitive or valuable personal data, once they are restored and released to the public or flow to the society, it will bring immeasurable losses. The data in the obsolete data store is at risk of revealing confidentiality, and the security of information is more important than ever.

Today's flash memory, commonly known as a USB flash drive, tends to be small in size. Although existing data storage devices can be easily destroyed by large devices, such large devices are not suitable for use in special environments, such as offices. The transportation of data storage devices to large-scale devices is inherently a transportation risk, and the operation of large-scale devices requires a certain amount of storage to be suitable for booting, which inevitably leads to risks in the storage process of data storage devices. Small devices that can be placed in the office avoid the aforementioned risks. Today's small devices use needles to pierce data memory, squeeze data memory, and cut data memory.

For example, the invention patent of the application number: 201320218109.3 uses the heat incineration to destroy the data. The invention patent of the application number: 201220030944.X uses two hobs to squeeze the pulverizing medium to destroy the data. The patent number of application number: 201320382900.8, 201210030309.6 is high. Piezoelectric destruction of electronic devices to destroy data, application number: 201220594154.4 invention patent using strong magnetic field magnetization to destroy data, application number: 200810200582.2 US US 8794559 B1 invention patent mechanically deform the hard disk to destroy data, application number: The 201410761807.7, 201310600024.6 invention patents mechanically break the memory to destroy the data.

However, the disadvantage of heating and burning is mainly that a large amount of toxic gas is generated, and the disadvantage of the hob squeeze and smash is not Can be crushed to be small enough to have a risk of leaking, high-voltage electric shock can not guarantee complete damage to the electronic device, strong magnetic field can not absolutely guarantee complete damage to the entire data, the hard disk deformation will leave a part of the data can be read, mechanically broken for the mechanical hard disk needs to disk The piece can be broken to be broken, and it can't be broken enough to be small enough to leak. And some of these devices have a very short life cycle, and some of them have very loud voices during work. The common disadvantage is that some small enough pieces of information can be read after processing.
