Corresponding File Systems
This device supports discs formatted with ISO9660 Level 1 or
Level 2.
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 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.
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).
