| CD-R / CD-RW | |
|---|---|
| CD-R | A CD-R can only be written one time (WORM). Tha data can’t be changed or erased later. The only possibility to add data later is to create a Multi-Session-CD where you can add another session later. Be aware of problems that might occur if you try to open a Multi-Session-CD on another computer. |
| CD-RW | A CD-RW can be erased and burned again with other content. Many CD-Players don’t accept CD-RWs and they are more expensive than CD-Rs. |
CD formats¶
| Most important CD formats | |
|---|---|
| Audio CD | Audio CDs can be played with most CD-Players (CD-Rs). The audio data is stored as PCM with two channels (stereo), a samplerate of 44.1 kHz and a bitrate of 16 bit/sample. |
| CD-ROM | CD-ROMs can be used to store data in files and folders. They may contain different filetypes on the same CD. They are primarily used to store data for usage with computers. Some DVD-Players are able to read CD-ROMs (only some audio- image- and video- file types and often only if no folders are used). |
