Ferry device

Abstract

The invention discloses a ferry device, which comprises a medium storage box, a data writing module, a data reading module and a ferry mechanism, and is characterized in that the medium storage box comprises an upper cover and a lower cover, the lower cover is provided with an opening, and a cavity for accommodating a data recording medium is formed between the upper cover and the lower cover; n groups of data writing modules and N groups of data reading modules are arranged; the data writing modules and the data reading modules are arranged on the circumference with the center of the ferry mechanism as the circle center in a spaced and crossed mode. According to the ferry device, the independent medium storage box is arranged, the medium storage box is connected to the rotary tray of theferry mechanism in a clamped mode, the ferry mechanism supports the medium storage box to drive the data storage medium to be transferred, and therefore safe transmission of data from an outer networkto an inner network or from the inner network to the outer network is achieved.

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
