摘要： A digital memory card includes a first area for storing a first file set having a set of audio objects and a second area for storing a second file set including a set of sound objects. A managing area is provided in the second file set and includes data for managing the first and the second file sets. Another memory card includes a first area for storing a set of sound files having a managing area, a second area for storing a still picture file and a third area for storing a motion picture file. The managing area stores data for managing the still picture and the motion picture files separately or together. The first and second file sets and the still picture and the motion picture files can be reproduced by a reproduction apparatus. Tune information is embedded in tune data as a digital watermark, the tune information being peculiar to the tune data. The tune information is further recorded in a file provided other than the tune data. The tune data with the embedded tune information and the file with the recorded tune information are distributed. The tune data is reproduced only when the tune information in the tune data and the file match each other.
