z

Track numbers may not be created in proper places,
depending on the source to be recorded from, such as
signals with noise.

z

The track numbers on the playback side may not
match the track numbers recorded on the MiniDisc.

z

When recording, if a programmed playback is per­formed by the source or playback is performed by
selecting tracks manually, the MiniDisc track numbers
may not be the same as on the source.

z

Track numbers may not be created properly, depend­ing on the connected stereo system.
