A recording/reproduction device that prevents content and related content from being reproduced simultaneously. The recording/reproducing device (110) includes a recording area (115), a communication processing unit (119) outputting the related content having details identical to details of the content recorded onto the recording area (115) into an external recording medium (160), and an encoding/decoding processing unit (117) obtaining unique information of the external recording medium (160). The encoding/decoding processing unit (117) changes a state of content recorded in the recording area (115) into an irreproducible state unless the unique information of the content is used, when the related content is outputted to the external recording medium (160), and then reproduces the content recorded in the recording area (115) using the unique information, when the encoding/decoding processing unit (117) obtains the unique information. |
