Abstract

An information recording method which can record audio and/or video information on a recording medium, while protecting previously recorded information from being overwritten. When recording new information on the record medium, the information recording method checks whether an intended recording position for new information corresponds to a start position of a previously recorded information region. If so, the method moves the recording position of new information into a recording termination position of the previously recorded information region.
