no. none of what you said is true. no data mode, mp3 ect. you can only write as audio files. normaly you can fit about 96 minutes per minidisc, but when you write in digital mode through a fiber optic connection, you can fit up to 5 hours of music. main benfit of minidiscs over mp3 players is that you can switch the discs. i have a minidisc because thats what im used to, however i recommend that you get a mp3 player instead.
