    • A song change detecting section and a frame boundary division section are provided. The song change detecting section reads, for example, a subcode corresponding to audio data read by a control section as song location information, and based on a song number included in the subcode, determines whether the audio data is located midway through a song or at a boundary between songs, and notifies the result. The frame boundary division section performs no process when a notification from the song change detecting section indicates that the audio data is located midway through a song, and writes dummy data into an encoded data buffer so that encoded data can be divided at a frame boundary and notifies the outside of a division location when the audio data is located at a boundary between songs. Thereby, in a recording/reproduction apparatus which performs reproduction and recording simultaneously, even when audio data including different song numbers is continuously input, encoded data can be divided into song numbers and recorded without interruption of reproduction.
    • 提供歌曲改变检测部分和帧边界分割部分。 歌曲改变检测部分例如读取与控制部分读取的音频数据相对应的子码作为歌曲位置信息,并且基于包含在子码中的歌曲号码,确定音频数据是位于歌曲中途还是位于歌曲的中途 歌曲之间的界限,并通知结果。 当来自歌曲改变检测部分的通知指示音频数据位于歌曲的中途时,帧边界分割部分不执行处理,并且将伪数据写入编码数据缓冲器,使得编码数据可以在帧边界被划分,并且 当音频数据位于歌曲之间的边界时通知分割位置的外部。 因此,在同时执行再现和记录的记录/再现装置中,即使连续输入包括不同歌曲号的音频数据,编码数据也可以被划分成歌曲号并记录而不会中断再现。
