Technical Field

Background

In data communication, data transmission or exchange can be performed between an internal network and an external network, between a public network and a private network, and between a secret network and a non-secret network, which have different security levels. In most cases, the security of data transmission needs to be guaranteed, and data exchange realized by wireless connection or wired connection cannot meet the requirement of a user on security, and a reliable way is to physically isolate two networks with different security levels for data transmission, and the operation mode is as follows: the method of data transfer using optical disc as carrier includes writing target data into blank optical disc in "network for providing data", and mechanically transporting optical disc carrying target data to "network for receiving data" for data storage.

Current data storage media primarily include optical disks, magnetic tape, and the like. Optical discs are often used to store important data as a stable storage carrier. The data ferrying process is that the data stored in the external network is recorded into a blank optical disc, and then the data stored in the recorded optical disc is stored in the internal network for storage. The ferry process can also be carried out by carrying the data in the internal network to the external network for storage.

In the existing physical isolation optical disc storage device, an optical disc is only used as a carrier for transferring data from an internal network to an external network or from the external network to the internal network, the optical disc is also transferred from the internal network to the external network or from the external network to the internal network in the data transfer process, the transfer process is often completed by a manipulator with a complex structure and a large volume, and the manipulator can generally only grab one optical disc at a time in the disc grabbing process, and the disc grabbing speed and the long-term reliability are low.
