Information storage medium, recording and reproduction apparatus, method of controlling recording and reproduction apparatus, control program, and communication system

摘要

An optical disk (100) stores operation identification information which causes a recording and reproduction apparatus (1) into which the optical disk (100) is inserted to recognize the optical disk (100) as a disk causing the recording and reproduction apparatus (1) to perform a commercial transaction over a network, and which serves as a trigger for causing the recording and reproduction apparatus (1) to perform the commercial transaction. Hence, by causing the recording and reproduction apparatus (1) to recognize the operation identification information before the contents is downloaded, it is possible to prevent important information such as personal information stored in the optical disk (100) from leaking over the network via the recording and reproduction apparatus (1). This as a result allows improvement in security against information leakage.
