  • Publication number: 20080134037
    Abstract: 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.

  • Publication number: 20070122114
    Abstract: In a recording apparatus equipped with a drive apparatus for recording data on a recording medium such as an optical disk, and a function capable of initializing a management information area of the recording medium, a storage unit is further provided. The storage unit stores thereinto initializing data which is used to be recorded on the management information area of the recording medium when the recording medium is initialized. In the case that an initializing operation is instructed, the recording apparatus records the initializing data which has been stored in the storage unit on the management information area of the recording medium from a beginning area thereof. Thus, a user no longer waits to use the recording medium until the initializing operation is accomplished when such a recording medium as a new optical disk is used, resulting in an improvement of user operability.
