How are MP3 files recorded
and played back?
MP3 "files (tracks)" can be recorded in "folders"
—in PC terminology.
During recording, the files and folders can be
arranged in a way similar to arranging files and
folders of computer data.
"Root" is similar to the root of a tree. Every file
and folder can be linked to and be accessed from
the root.
The illustration below shows an example of how
MP3 files are recorded on a CD-R or CD-RW,
how they are played back, and how they are
searched for on this unit.
Notes:
• This unit can read a CD-ROM containing MP3
files. However, if non-MP3 files are recorded
together with MP3 files, this unit will take a longer
time to scan the disc. It may also cause the unit to
malfunction.
• This unit cannot read or play an MP3 file without
the extension code <.mp3>.
• This unit is not compatible with MP3 file encoded
with Layer 1 and Layer 2 formats.
• This unit is not compatible with Playlist**.
** A playlist is a simple text file, used on a PC, which
enables users to make their own playback order
without physically rearranging the files.
