Producing MP3/WMA/AAC discs
MP3/WMA/AAC files are prepared, then written to a CD-R or CD-RW
using CD-R writing software. A disc can hold up to 509 files/folders
(including Root Folders), and the maximum number of folders is 255.
Playback may not be performed if a disc exceeds the limitations
described above.
Media supported
The media that this device can play back are CD-ROMs, CD-Rs, and
CD-RWs.
Corresponding File Systems
This device supports discs formatted with ISO9660 Level 1 or Level 2.
Under the ISO9660 standard, there are some restrictions to remember.
The maximum nested folder depth is 8 (including the root directory).
The number of characters for a folder/file name is limited.
Valid characters for folder/file names are letters A-Z (all caps), numbers
0-9, and ‘_’ (underscore).
This device also can play back discs in Joliet, Romeo, etc., and other
standards that conform to ISO9660. However, sometimes the file
names, folder names, etc., are not displayed correctly.
Formats supported
This device supports CD-ROM XA, Mixed Mode CD, Enhanced CD
(CD-Extra) and Multi-Session.
This device cannot correctly play back discs recorded with Track At
Once or packet writing.
Order of files
Files are played back in the order that the writing software writes them
to the disc. Therefore, the playback order may not be what is expected.
Verify the writing order in the software’s documentation. The playback
order of the folders and files is as follows.
* The folder No./ folder Name will not be displayed if no readable file is
contained in the folder.
Bit rate
This is the “sound” compression rate specified for encoding. The higher
the bit rate, the higher the sound quality, but also the larger the files.
Sampling rate
This value shows how many times per second the data is sampled
(recorded). For example, music CDs use a sampling rate of 44.1 kHz, so
the sound is sampled (recorded) 44,100 times per second. The higher
the sampling rate, the higher the sound quality, but also the larger the
volume of data.
Encoding
Converting music CDs, WAVE (AIFF) files, and other sound files into the
specified audio compression format.
Tag
Song information such as track titles, artist names, album names, etc.,
written into MP3 files.
Root folder
The root folder (or root directory) is found at the top of the file system.
The root folder contains all folders and files. It is created automatically
for all burned discs.
