Description
Technical field
The present invention relates to data storage and data transfer, more particularly to a kind of physical isolation formula data one-way transmission apparatus and
Method.
Background technology
In data communication, can be between different level of security networks between internal networking and external network, or public network
Between network and private network, and between secrecy net and unclassified net.In order to realize and ensure the safety of network data exchange process, most
The mode of safety is exactly separating for physics, realizes that different stage is internetwork " physical isolation ".
Current data storage medium mainly includes CD, disk, tape etc..CD carries as a kind of storage of stabilization
Body, it is usually used to preserve significant data.In the storing process of data, the data carving of outer net will be stored in first to the light of blank
In disk, then it will be preserved in the data Cun Chudao Intranets deposited in the good CD of imprinting.
In existing physical isolation optical disk storage apparatus, CD only as by data from Intranet be transferred to outer net or
The carrier of Intranet is transferred to from outer net, CD will be also transferred in outer net from Intranet in the transfer process of data, or from outer
Net is transferred in Intranet, and the process shifted is often completed by the larger manipulator of complicated, volume.
