What is the differences between the audio and data Cd's?
Audio CDs can be played by CD players and radios. The music CDs
of your favorite artists that you buy are audio CDs, and they have
nothing on them except audio signal.
Data CD is a CD that can contain different types of data such as
photos, videos, mp3 files, text files, etc. Data CDs are normally
usable only on computers. However, there are radios and DVD-players
that can scan through a data CD and find files that can be played
on that particular player (for example, mp3 files).
