The present invention also provides a playback device where playback can be achieved without mixing the simple control region (simple U-TOC) with the control region (U-TOC) for the audio and general data and, by also recording copy-protection information at the simple control region, a playback operation from a recording medium (1) which has been copied illegally will not be possible.
