摘要 |
The present invention relates to a recording medium recorded with audio data and general data (including image data for computers and character data) mixed together, provided with data for each control region, where by providing a special simple control region, editing of complicated control regions does not have to be carried out and a memory region is not necessary as a working region for editing. The present invention also provides a playback device where playback can be achieved without mixing the simple control region with the control region 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 which has been copied illegally will not be possible. The present invention further relates to a recording device for updating each control region while data updating is being carried out at the recording medium.
