They are special discs andmay not play on the CR401.Discs made on personal computersDiscs made on personal computers, includingthose of a compatible format, may not workproperly in the CR401 because of incorrectsettings in the disc burning software. Ch

24、 Supported formats: Mode 1,Mode 2. Folders can be up to eight levels deep.MP3 files must be MPEG-1/MPEG-2 Audio Layer3 format with a sampling rate of between 16 kHzand 48 kHz and a bit-rate of between 32 kbps and320 kbps (128 kbps or 192 kbps recommended).Incompatible files cannot be played. Fixed b

25、it-rate MP3 files are recommended,however, variable bit-rate (VBR) MP3 filesbetween 8 kbps and 320 kbps are supported(Playing times may display incor-rectly). MP3 files must have a “.mp3” or “.MP3” filename extension. MP3 files without the properextension will not be recognized. To preventnoise and

26、malfunction, do not use theseextensions for other types of files. The CR401 supports up to 500 MP3 files and upto 200 folders per disc. (In this case, Disc andFile names contain 30 characters and Foldernames contain 20 characters.) Files and foldersin excess of this cannot be played. Note that ifthe

27、 file and folder structure is very complicated,the CR401 may not be able to read or play all ofthe MP3 files on the disc. If the disc, folder or filenames contain many characters, the CR401may not support 500 MP3 files. Disc names may contain up to 30 characters.File and folder names may contain up

28、to 60characters. The maximum time that can be displayed for asingle track is 99 minutes and 59 seconds. The remaining time cannot be displayed whenplaying MP3 files.Multisession discs are supported, however,some multisession discs may take a long time toload and some may not load at all. When burnin

29、gCDs we recommend that you use a singlesession (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 thatcontain many files and folders, and files otherthan MP3s, it may take a long time to read thedisc. We recommend that you include o

30、nly MP3files on your discs, use about 20 folders, andlimit folder nesting to three levels deep.
