The tape data read from the head 1 passes through the reproducing amplifier 3, is converted into a digital signal by the AD converter 14, and is input to the audio/additional information switching circuit 6.
音声・付加情報切換回路６は付加認識信号に含まれる付
加情報認識信号を識別し、音声信号の時には、出力増幅
器７を通して音声出力Ｖ。ＵＴとして外部へ出力する。The audio/additional information switching circuit 6 identifies the additional information recognition signal included in the additional recognition signal, and when it is an audio signal, outputs the audio V through the output amplifier 7. Output to the outside as UT.
付加情報の時には、制御部１０へ入力され、制御部１０
は付加情報をデコードして表示回路１３に供給し、表示
回路１３で付加情報が表示される。When the additional information is inputted to the control unit 10, the control unit 10
decodes the additional information and supplies it to the display circuit 13, where the additional information is displayed.
なお、付加情報と音声信号を区別する付加情報認識信号
は、例えば、音声信号を記録する周波数帯域（２０〜２
０ｋＨｚ）より高い周波数帯域を使って記録される。Note that the additional information recognition signal that distinguishes additional information and audio signals is, for example, in the frequency band (20 to 2
recorded using a frequency band higher than 0 kHz).
第２図は本発明の第２の実施例のブロック図である。FIG. 2 is a block diagram of a second embodiment of the invention.
第２図に示ずように、第２の実施例では、付加情報と付
加情報認識信号から成る付加認識信号のうち、ヘッド１
