Inter-network physical isolation data device and system

Abstract

The invention provides an inter-network physical isolation data device and system. The inter-network physical isolation data device comprises: a base; an optical disk driver main shaft motor, which is arranged on the base and is provided with a first motor contact, a second motor contact, and an optical disk driver main shaft; a first optical reading device, which is provided with an external network contact, and the external network contact is in contact with the first motor contact, so as to record the external network data on an optical disc; a second optical reading device, which is provided with an inner net contact, and the inner net contact is in contact with the second motor contact; when the outer net contact is in contact with the first motor contact, the inner net contact and the second motor contact are in a separated state, the projection of the second optical reading device in the direction perpendicular to the optical disc is staggered from the optical disc; when the inner net contact is in contact with the second motor contact, the outer net contact and the first motor contact are in a separated state, and the projection of the first optical reading device in the direction perpendicular to the optical disc is staggered with the optical disc. According to the scheme, the security of the network switching process can be realized, and the ferrying efficiency is improved.

Description

technical field [0001] The invention relates to the field of data ferry technology, in particular to a device and system for physically isolating data between networks. Background technique [0002] In data communication, networks with different security levels can be between internal networks and external networks, or between public networks and private networks, and between confidential networks and non-confidential networks. In order to realize and ensure the security of network data exchange process, The safest way is physical separation to achieve physical isolation between different levels of networks. [0003] Current data storage media mainly include optical discs, magnetic disks, and magnetic tapes. As a stable storage carrier, optical discs are often used to save important data. In the process of data storage, first burn the data stored in the external network to a blank CD, and then store the data stored in the burned CD to the internal network for preservation....
