  • Storage medium playback system and method
    Patent number: 6283764
    Abstract: A first reading unit reads data stored in a second storage area of a storage medium (including reproduction management information), and stores it in another storage medium. A first reproducing unit reproduces the data read from a first storage area of a storage medium by the first reading unit. A second reading unit reads data stored by the first reading unit in another storage medium, and outputs it to a second reproducing unit. The second reproducing unit reproduces data received from the second reading unit. A controlling unit synchronizes the reproduction of the data by the first reproducing unit with the reproduction of the data by the second reproducing unit.
