Claim:
An information processing device comprising: a processor configured to: determine whether or not a basic stream that can be reproduced singly and an extended stream used for reproduction with the basic stream forming a video stream of contents to be copied are interleaved with respect to each data in a predetermined unit and recorded in a first recording medium, based on control information as information for controlling reproduction of the contents recorded in the first recording medium, and change a value of recording status information representing whether or not the basic stream and the extended stream are interleaved with respect to each data in the predetermined unit and recorded contained in the control information to a value representing that the streams are not interleaved but recorded; and a recording controller, in the case of a determination that the basic stream and the extended stream are interleaved with respect to each data in the predetermined unit and recorded, configured to: designate a first file among the first file that manages the basic stream, a second file that manages the extended stream, and a third file that manages the basic stream and the extended stream, copy the basic stream from the first recording medium to a second recording medium, designate the second file and copy the extended stream from the first recording medium to the second recording medium, and record the control information containing the recording status information in which the value has been changed in the second recording medium.
