A data transmission device and method

Abstract

The invention discloses a data transmission device, which comprises a data recording medium, a data writing module, a data reading module and a ferry mechanism, and the data writing module and the data reading module are intersected and arranged on the ferry mechanism the center of which is the center of the circle; the ferry mechanism is used to support the data recording medium and drive the data recording medium to move between the data writing module and the data reading module. The invention sets a plurality of independent optical drives to respectively write and read data, and realizes that while data is written in a part of the data recording medium, data in another part of the data recording medium is read, and then the two groups are driven by the ferry mechanism. The data recording medium is moved to the designated position, and the data writing and reading are continued, which greatly improves the data transmission efficiency.

Description

technical field [0001] The invention relates to the fields of data storage and data transmission, in particular to a data transmission device and method. 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",...

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
