If a disc has both music data (CD-DA)
and MP3 files, playback of the two file
types differs depending on how the
disc was recorded.
l
Packet written discs cannot be played
on this unit.
l
This unit does not play CDs recorded
using MP3i (MP3 interactive), MP3
PRO and RIFF MP3 formats.
About folders and files
l
The order of hierarchy for MP3 files
and folders during playback or other
functions is from shallow to deep. The
arrangement and playing order of a
recorded disc containing MP3 files is
as follows:
l
File number
A numerical file number is assigned
to each file in a folder starting from
the deepest hierarchy.
l
Folder number
A numerical folder number is
assigned to each folder starting from
the deepest hierarchy.
NOTE
Folders and tracks (files) within the same
hierarchy play in the order they were written to
the disc depending on the write software.

: Track (File) : Folder
l
The folder order is automatically
assigned and this order cannot be
optionally set.
l
Any folder without an MP3 file will be
ignored. (It will be skipped and the
folder number will not be displayed.)
l
MP3 files not conforming to the MP3
format containing both header frames
and data frames will be skipped and
not played.
l
This unit will play MP3 files that have
up to eight levels. However, the more
levels a disc has, the longer it will take
to initially start playing. It is
recommended to record discs with two
levels or less.
l
A single disc with up to 512 files can
be played and a single folder with up to
255 files can be played.
l
When naming an MP3 file, be sure to
add an MP3 file extension (.mp3) after
the file name.
