Method and apparatus for recording text data

A method of recording text-data, comprising the steps of:

• forming 1) first text data relating to audio data and being non-copyrighted, 2) a flag representing that the first text data are non-copyrighted, 3) an information piece representing a character code used for the first text data, and 4) an information piece representing a size of the first text data into a first text block;
• forming 1) second text data relating to the audio data and being copyrighted, 2) a flag representing that the second text data are copyrighted, 3) an information piece representing a character code used for the second text data, and 4) an information piece representing a size of the second text data into a second text block;
• generating an item text including at least one of the first and second text blocks;
• generating a text-data management structure including the item text;
• and
• recording the text-data management structure on an audio disc.

A computer program for recording text-data, comprising the steps of:

• forming 1) first text data relating to audio data and being non-copyrighted, 2) a flag representing that the first text data are non-copyrighted, 3) an information piece representing a character code used for the first text data, and 4) an information piece representing a size of the first text data into a first text block;
• forming 1) second text data relating to the audio data and being copyrighted, 2) a flag representing that the second text data are copyrighted, 3) an information piece representing a character code used for the second text data, and 4) an information piece representing a size of the second text data into a second text block;
• generating an item text including at least one of the first and second text blocks;
• generating a text-data management structure including the item text;
• and
• recording the text-data management structure on an audio disc.

An apparatus comprising:

• first means for deciding whether or not text data relating to audio data are copyrighted, and generating a first signal representing a result of said deciding;
• second means for deciding a character code set expressing the text data, and generating a second signal representing the decided character code set;
• third means for formatting 1) the text data, 2) the first signal generated by the first means, and 3) the second signal generated by the second means into a text-data management structure;
• and
• fourth means for recording the text-data management structure generated by the third means on an audio-data recording disc.
