Abstract: A recording device records contents in a plurality of recording media. While the recording device records a content in a recording medium, if a free space of the recording medium runs out, an unrecorded part of the content needs to be recorded in another recording medium. In order to play back all parts of the content, all recording media in which all the parts of the content have been separately recorded are necessary. Particularly, if an internal recording medium included in the recording device has a small space and accordingly a sufficient space is secured by connecting an external removable recording medium to the recording device after the recording has started, parts of the content are separately recorded in the internal recording medium and the external recording medium.

Abstract: A data IO device acquires stream data that includes CCI (copy control information) and outputs the stream data after finalizing a content of the CCI. Specifically, the data IO device sequentially acquires stream data including CCI, judges whether all stream data acquired within a predetermined time period includes the same CCI, and processes all stream data acquired during the predetermined time period in accordance with the same copy control information if judged in the affirmative.
