ABSTRACT:
In an apparatus and method for recording and playing back audio and video data using an IC card memory as a recording medium, the apparatus is composed of an index region in which card attributes and miscellaneous intrinsic card data are recorded, a mode code region in which data for setting a recording or a playback type of chapter is recorded, a chapter pointer in which the address where each chapter starts in a memory region is recorded, and a data region in which the actual data of each chapter is stored. The method includes the steps of selecting a predetermined chapter and recording mode, recording a code of the selected mode in the mode address of the selected chapter, recording a starting address of the chapter in a pointer address if a recording key input is detected, recording a mode monitoring code in the starting address and recording data corresponding to the subsequent addresses, and recording data indicating the end of the chapter if data input is completed. Therefore., the apparatus and method according to the present invention can record and play back audio and/or video data concurrently or separately.
