Publication number: 20080134037Abstract: When any undubbed data out of the recorded data in a hard disk device, is dubbed to a DVD, it sometimes occurs that dubbing-completed data and undubbed data are mixed together in the hard disk. For this reason, it is not easy to select only the undubbed data before start of dubbing processing. In a recording and reproducing device including a dubbing function, dubbing of recorded data is made from the first recording media (e.g., a hard disk) to the second recording media (e.g., a DVD), and at that time, only the recorded data of an undubbed item selected from the menu, etc., is displayed before start of dubbing. Also, if the above recorded data of the dubbing source cannot be contained in a single DVD, then which recorded data is to be dubbed to second, third, or what other number of media, according to the recording media used by the dubbing destination, is displayed before dubbing processing.Type: ApplicationFiled: October 4, 2007Publication date: June 5, 2008Inventors: Masahiro Fujimoto, Yuichi Katano, Keiji Nagayama
