A system control circuit 5 determines whether or not an external apparatus connected to an interface 14 is one that can store data, by transmitting data to the apparatus through the interface 14. It the system control circuit 5 determines that the external apparatus can store data, the circuit 5 turns off a switch 13, stopping the transmission of audio data to the external apparatus through the interface 14. As a result, illegal copying of the data can be effectively prevented.

When the user designates the reproduction of searching audio data, the designated searching audio data and audio volume data are read from a searching data recording portion. The searching audio data is reproduced corresponding to the audio volume data. When the user designates the reproduction of main audio data, the selected audio data is read from a disc and reproduced. In addition, number-of-reproduction-times data, audio volume data, audio quality data, and time period data for the designated main audio data that are updated in the searching data storing portion. The searching audio data corresponding to the designated main audio data is read from the disc corresponding to the audio quality data and the time period data and recorded to the searching data storing portion.
