A contents data reproducing apparatus that continuously reproduces pieces of music without producing a soundless state between music pieces is provided. When a pickup 2 finishes reading of reproducing object piece of audio data, a microcomputer 10 stops writing of the audio data into a storage unit
A contents data reproducing apparatus that continuously reproduces pieces of music without producing a soundless state between music pieces is provided. When a pickup 2 finishes reading of reproducing object piece of audio data, a microcomputer 10 stops writing of the audio data into a storage unit 4 and makes the pickup move to a front of the next reproducing object piece of audio data to start reading of the next reproducing piece of audio data. Then, when a result in a level detection unit 7 shows that the level of the next reproducing object piece of audio data is higher than the reference level, then, writing of the next reproducing object piece of audio data, which is read by the pickup 2, into the storage unit 4 is started. An audio data conversion unit 8 reads the audio data stored in the storage unit 4 and reproduces it.
