Abstract
To provide a highly user-friendly content moving device which prevents unauthorized copying of content and, when content that has been irreversibly converted and moved to a recording medium is moved back to a move source, can use the content in its form before irreversible conversion. A partial information extraction unit extracts, from content stored on a content storage unit, partial data necessary for playback of the content, and a write/read unit writes the partial data to a partial information storage unit and overwrites a portion of the content corresponding to the partial data with different data, while a conversion unit transcodes the content and writes the transcoded content and the partial data to the recording medium.
