Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a recording / recording prevention automatic switching method and a recording / recording prevention automatic switching apparatus for a cassette tape, and a recording tap for preventing recording of a video cassette tape and a recording tap detection switch for detecting the same. The video cassette tape is automatically switched to the enabled mode or the non-recordable mode, thereby providing convenience of using the video cassette tape.

In the present invention, a memory is mounted at a proper position of a video cassette and data is read from the memory when the cassette is loaded, thereby determining a recording / non-recording mode. If the determined result is not recordable or is a recording mode, the controller transmits the abnormal state as a message and corrects the recording mode or the non-recording mode according to the user's intention, thereby performing recording or ejecting.
