Method for recording and reproducing catalog information

PURPOSE: A method for recording and reproducing catalog information is provided to freely read contents of catalog from catalog information to audio data while reproducing the audio data stored on a DVD disk. CONSTITUTION: A signal read from a disk(210) is restored into a digital signal to be applied to a buffer memory(250). Audio data of playback information is recorded on an audio buffer(251) and catalog data of the playback information is recorded on a video buffer(252). The catalog data is read according to a control signal generated from a system control unit(240), and is restored into a video signal through a video decoder(270). The system control unit generates an appropriate control signal to output catalog data to be reproduced. An audio decoder(260) restores the encoded audio data into the original audio and additional information.
