Thanks for your question.
According to CDR Info, the only reason audio CDRs exist is because of
home CD Writers. These CD writers will only write to audio CDRs. PC CD
writers/rewriters dont make the distinction between the two.
basically the 'Audio' CD-Rs/CD-RWs have a specific byte of data
written right at the beginning in one of the sub channels, the home
systems will ONLY write to these discs.
As far as PC CD-R(W) drives are concerned there is no difference
between the 2, the quality is the same, the media is the same, it will
ignore the info specifically set for the home players.
You can create audio CDs using regular CDRs, which appear to be
cheaper than audio CDRs.
According to Verbatim:
Verbatim MusicLifePlus CD-R discs are audio-only CD-R discs designed
specifically for use in home audio CD-R recording systems.
There is also some discussion on the quality of audio CDRs versus the
regular data type. Anecdotal evidence suggests that there is very
little difference in the quality, although it will depend on the
quality of the CDR you have purchased.
This discussion post at CDFreaks.cm also sheds some light on the
So the general feeling seems to be that unless you are recording CDs
using a home audio CD-R recording system, you don't have to use the
audio CDR discs unless you choose to.
