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 is characterized in that the data writing module and the data reading module are arranged on a circumference taking the center of the ferry mechanism as a circle center in a spaced and crossed manner; and the ferry mechanism is used for supporting the data recording medium and driving the data recording medium to move between the data writing module and the data reading module. According to the device, a plurality of independent CDdrivers are arranged for writing and reading data respectively; the data in the other part of the data recording medium are read while the data is written into one part of the data recording medium,and then the ferry mechanism drives the two groups of the data recording media to move to the specified positions to continuously write and read the data, so that the data transmission efficiency is greatly improved.

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
