  • Patent number: 7706221
    Abstract: Disclosed herein is an information recording/reproducing apparatus that includes a first and a second recording/reproducing modules, a buffer memory to store information temporally, and a control module that switches between a first mode and a second mode when the information is dubbed from the first recording/reproducing module to the second recording/reproducing module. In the first mode, information in the first recording/reproducing module is reproduced and stored in the buffer memory. In the second mode, the information stored in the buffer memory is recorded in the second recording/reproducing module. The apparatus further includes a temperature detecting module. Depending on the temperature detected by this module, the apparatus changes the movement of the second recording/reproducing module in the first mode and the movement of the first recording/reproducing module in the second mode.

  • 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.
