Disc Notes
Supported Discs
The CR-505DAB supports the following discs.
• Some audio CDs use copy protection that doesn’t con-
form to the official CD standard. Since these are non-
standard discs, they may not play properly in the CR-
505DAB.
• The CR-505DAB supports CD-R and CD-RW discs.
However, some CD-R and CD-RW discs may not work
properly for any of the following reasons: disc burner
characteristics, disc characteristics, the disc is damaged
or dirty. See the manual supplied with your disc burner
for more information. Condensation or dirt on the optical
pickup lens can also affect playback.
• The CR-505DAB supports 8 cm and 12 cm discs.
• Playback is not available for DTS CD.
• The CR-505DAB does not support disc types not listed.
• Don’t use discs with an unusual shape, such as those
shown below, because you may damage the CR-
505DAB.
• Don’t use discs that have residue from adhesive tape,
rental discs with peeling labels, or discs with custom-
made labels or stickers. Doing so may damage the CR-
505DAB and you may not be able to remove the disc
properly.
Discs Made on Personal Computers
Discs made on personal computers, including those of a
compatible format, may not work properly in the CR-
505DAB because of incorrect settings in the disc burning
software. Check the manual supplied with your disc burning
software for additional compatibility information.
MP3 Compatibility
• MP3 discs must be ISO 9660 Level 1 or Level 2, Romeo
or Joliet compliant. Supported formats: Mode 1, Mode 2
XA Form 1.
• Folders can be up to eight levels deep.
• MP3 files must be MPEG-1/MPEG-2 Audio Layer 3 for-
mat with a sampling rate of between 16 kHz and 48 kHz
and a bit-rate of between 32 kbps and 320 kbps (128 kbps
or 192 kbps recommended). Incompatible files cannot be
played.
• Fixed bit-rate MP3 files are recommended, however, vari-
able bit-rate (VBR) MP3 files between 8 kbps and 320
kbps are supported (Playing times may display incor-
rectly).
• MP3 files must have a “.mp3” or “.MP3” file name exten-
sion. MP3 files without the proper extension will not be
recognized. To prevent noise and malfunction, do not use
these extensions for other types of files.
• The CR-505DAB supports up to 500 MP3 files and up to
200 folders per disc. (In this case, Disc and File names
contain 30 characters and Folder names contain 20 char-
acters.) Files and folders in excess of this cannot be
played. Note that if the file and folder structure is very
complicated, the CR-505DAB may not be able to read or
play all of the MP3 files on the disc. If the disc, folder or
file names contain many characters, the CR-505DAB
may not support 500 MP3 files.
• Disc names may contain up to 30 characters. File and
folder names may contain up to 60 characters.
• The maximum time that can be displayed for a single
track is 99 minutes and 59 seconds.
• The remaining time cannot be displayed when playing
MP3 files.
• Multisession discs are supported, however, some mul-
tisession discs may take a long time to load and some may
not load at all. When burning CDs we recommend that
you use a single session (disc-at-once), and select “Disc
Close.”
• The ID3 tag version 1.0 is supported.
Notes:
• With CD-ROM, CD-R, and CD-RW discs that contain
many files and folders, and files other than MP3s, it may
take a long time to read the disc. We recommend that you
include only MP3 files on your discs, use about 20 fold-
ers, and limit folder nesting to three levels deep.
• In this manual, MP3 files are referred to as tracks.
