Physical isolation type compact disc read-write device

Abstract

The invention relates to the field of CD juke-boxes, and discloses a physical isolation type compact disc read-write device. The physical isolation type compact disc read-write device comprises an intranet controller, an extranet server, a switch, a sensor, a blank CD cassette, a recordable CD driver, a CD-ROM, a recycled CD cassette, a CD extractor and a CD catcher, wherein CD extraction of the CD extractor, CD catching of the CD catcher and CD writing of the recordable CD driver are finished under the control of the intranet controller; the intranet controller controls a read-only tray to be popped up or closed through the switch; the extranet server controls the CD-ROM to carry out CD reading and pop up the read-only tray after reading; the sensor sends the detected information of popping up of the read-only tray, namely the information of finishing of CD reading to the intranet controller; the intranet controller controls a manipulator to put a read CD to the recycled CD cassette. The physical isolation type compact disc read-write device is compact in structure, can achieve unidirectional transmission of data and improves the information safety.

Description

technical field [0001] The invention relates to the field of optical disk libraries, in particular to a physically isolated optical disk reading and writing device. Background technique [0002] As a resource, information is of special significance to human beings due to its universality, sharing, value-added, processability and multi-utility. China's reform and opening up has brought about a sharp increase in the amount of information in all aspects, and requires large-capacity and high-efficiency transmission of this information. Both institutions and individuals are entrusting more and more tasks to computers, and sensitive information is being transmitted between computer systems through fragile communication lines. [0003] In such an information age background, information security work is particularly important. The essence of information security is to protect important information resources from various types of threats, interference and destruction, that is, to en...

Problems solved by technology

[0004] In the process of storage, processing and exchange of information, there is a possibility of leakage. In the CDs stored in the CD library, information security accidents are often caused due to the sharing of information from the internal network and the external network, resulting in the leakage of confidential information.
