PROBLEM TO BE SOLVED: To provide a recording and reproducing device which prevents the erroneous editing of titles when the title data of the digital music data recorded by an ATRAC 3 compression system is edited by a model not dealing with the ATRAC 3. SOLUTION: This recording and reproducing device 1 decides whether an identifier 'LP:' is included in the title data included in the UTOC information of the digital music data recorded at an MD or not. The device switches the editing method according to the result of this decision and prohibits the edition of the title data including this identifier to put the identifier into a state that the identifier cannot be deleted. As a result, the identifier is prevented from being erroneously deleted by a user. |
