RECORDING/REPRODUCTION DEVICE

摘要

There is provided a recording/reproduction device capable of disabling reproduction of a content having the same content as the outputted content, simultaneously with the outputted content and capable of reproducing it as a high-quality content during reproduction. The recording/reproduction device (110) includes: a recording area (115); a communication unit (119) for outputting the related content as a content having the same content as the content recorded in the recording area (115) to an external recording medium (160); and an encryption/decryption unit (117) acquiring unique information on the external recording medium (160). When the related content is outputted to the external recording medium (160), the encryption/decryption unit (117) modifies the content recorded in the recording area (115) to a state that the content cannot be reproduced unless its unique information is used by using the unique information. When the unique information is acquired later, the unique information is used to reproduce the content stored in the recording area (115).
