Abstract: PURPOSE: A recording method of a recordable disk is provided to prevent illegal copy except for private purposes and to record the authenticated data of content on a disk or through other channels by copying the content available for single or free copy selectively depending on watermark or copy control data and not recording no-copy content. CONSTITUTION: An input interface receives various kinds of contents through plural transfer channels to process the contents depending on authentication. If the content is authenticated digital content, the content is decided in availability for copy. In case of content unavailable for copy, a title key of the content encoded through a content decoder is generated to decode the content. If the content input through the interface is analog content of video or audio data, the content is decided in availability for copy. In case of unavailable for copy, the content is not recorded. Otherwise, the analog content is converted into digital content through a content A/D converter and output to a content watermark confirm unit. The content watermark confirm unit receives non-authenticated digital content directly through the interface or decoded content through the content decoder, and detects the watermark of the input content. The confirm unit does not record the content if the content is unavailable for copy, and remarks the content if the content is within an available range for copy. Finally, the content for free copy or the remarked content is recorded.
