Abstract
An information recording and reproduction apparatus uses a recording medium that contains information which prohibits digital copying. A reproduction section reproduces the desired informatiion stored on a first recording medium. A recording section records the reproduced output at a desired position on a second recording medium. However, an erasing section erases the information from the first recording medium during the process of recording that information on the second recording medium. The first and/or second recording medium cannot be removed from the information recording and reproduction apparatus until the erasing operation is completed.
