This device may not play back correctly depending on sampling rates.

ID3 tagsIWMA tags

This device supports 103 tag v1 and v2, and WMA tag.

If tag data is in an MP3/WMA/AAC file, this device can display the title (track title), artist name, and album name 103 tag/WMA tag data.

This device can only display single-byte alphanumeric characters (up to 30 for 103 tags and up to 15 for WMA tags) and the underscore. For non-supported characters, the display is blank.

The tag information may not be correctly displayed, depending on the contents.

Producing MP3IWMAJAAC discs

MP3/WMA/AAC files are prepared, then written to a CO-R or CO- RW using CO-R writing software. A disc can hold up to 510 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, CO-Rs, and CO-RWs.

Corresponding File Systems

This device supports discs formatted with IS09660 Level 1 or Level 2.

Under the IS09660 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 IS09660. 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.

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 of44. 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 ofdata.

Encoding

Converting music CDs, WAVE (AIFF)files, and other soundfiles into the specified audio compression format.

Tag

Song information such as track titles, artist names, album names, etc., written into MP3IWMAlAACfiles.

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.
