a ferry device

Abstract

The invention discloses a ferry device, comprising a medium storage box, a data writing module, a data reading module and a ferry mechanism, the medium storage box includes an upper cover and a lower cover, the lower cover is provided with an opening, the A cavity for accommodating data recording media is formed between the upper cover and the lower cover; there are N groups of the data writing module and the data reading module; the data writing module and the data reading module The modules are intersected at intervals on a circle centered on the center of the ferry mechanism. The ferry device of the present invention is provided with an independent medium storage box, and the medium storage box is clamped on the rotating tray of the ferry mechanism, and the medium storage box is supported by the ferry mechanism to drive the transfer of the data storage medium, thereby realizing the transfer of data from the external network Secure transmission to intranet or intranet to extranet.

Description

technical field [0001] The invention relates to the fields of data storage and data transmission, in particular to a ferry device. Background technique [0002] In data communication, the transmission or exchange of data can be carried out between the internal network and the external network, between the public network and the private network, between the confidential network and the non-confidential network, and these networks have different levels of security and confidentiality. In most cases, it is necessary to ensure the security of the transmitted data, but data exchange relying on wireless connection or wired connection cannot meet the user's security requirements. The more reliable way is to use two networks with different security levels for data transmission. Carry out physical isolation, and its operation method is: use the optical disc as the carrier for data transfer, burn the target data into a blank disc in the "data-providing network", and then mechanically ...

AI Technical Summary

Problems solved by technology

[0004] In the existing physically isolated optical disk storage devices, the optical disk is only used as a carrier for transferring data from the internal network to the external network, or from the external network to the internal network. During the data transfer process, the optical disk is also transferred from the internal network to the external network. In the network, or from the external network to the internal network, the transfer process is often completed by a complex and large-scale robot. In the process of grasping the disk, the robot can usually only grasp one disc at a time, and the grasping Disk speed and long-term reliability are lower
