ID3 tags/WMA tags This device supports ID3 tag v1.0, v1.1, v2.2, v2.3, v2.4, and WMA tag Ver.1.x. If tag data is in an MP3/WMA/AAC file, this device can display the title (track title), artist name, and album name ID3 tag/WMA tag data (maximum 64 characters). For non-supported characters, "?" is displayed. The number of characters may be limited, or not correctly displayed, depending on the tag information. Playing back MP3/WMA/AAC MP3/WMA/AAC files are prepared, then written to a CD-R, CDRW (DVD-R/DVD-RW/DVD+R/DVD+RW) using CD-R writing software and Flash memory. • Maximum numbers of playable files/folders Disc: 1,000 files/folders (including Root Folder/DivX® file) Flash memory: 10,000 files/folders (including Root Folder/ DivX® file) • Largest playable file size: 512 MB Playback may not be performed if a disc exceeds the limitations described above. If a file/folder name is long, the maximum possible number of files may decrease. • Both Audio and Video files are counted if their formats are playable on this unit. Media supported The media that this device can play back are CD-ROMs, CD-Rs, CD-RWs, DVD-Rs, DVD-RWs, DVD+Rs, DVD+RWs and Flash memory. Corresponding File Systems This device supports discs formatted with ISO9660 Level 1 or Level 2, UDF1.02 and UDF1.02(ISO Bridge). Under the ISO9660 standard, there are some restrictions to remember. The maximum nested folder depth is 8 (including the root directory). File names are limited to 256 characters (including the extension). Valid characters for folder/file names are letters A-Z (all caps), numbers 0-9, and '_' (underscore). This device 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 Mode1, CD-ROM XA Mode2(Form1&2), Mixed Mode CD 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's expected. Verity the writing order in the software's documentation. The playback order of the folders and files is as follows. (The following numbers may differ from actually displayed numbers.) Root Folder Folder MP3/WMA/AAC File Terminology 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/WMA/AAC 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. 36-EN
