Abstract: The present invention relates to a method and apparatus for recording an audio signal on an integrated circuit (IC) memory card. The audio signal to be recorded is considered to have plural chapters (i.e., songs, or distinct movements) with a mute section (i.e., moment of silence of at least a predetermined length) between each adjoining chapter in the audio signal to be recorded. The present invention provides for automatic partitioning between the chapters as they are recorded on a data area of the IC memory card even when the audio signal is recorded continuously based upon a single press of the record button and terminated with a single press of the stop button. Since the chapters of the recorded audio signal are automatically partitioned, without need for starting and stopping of the recording process by a user, a recording is conveniently made on the IC memory card which allows random access to any one of the chapters for playback.
