CD-R Media Types...Audio vs. Data
Posted: Wed Feb 23, 2005 1:22 pm
Crew,
Got my new Plextor Premium (wound up with an internal after all...the internet resellers I had lined up turned out to be BSr's...claiming to have the external available; & then being out of stock.)
The install went without a hitch; & thanks for everyone’s help.
So...I started to get my feet wet with the PlexTools software...burned a few discs on different media; & then checked those burns for C1, C2 & CU errors.
First, I burned two musical compositions to a blank Verbatim CD-R (which came with the drive.)
Then I broke out a TDK blank from a bulk tub I grabbed at CompUSA; & burned the same two tunes.
The C1 (BLER) error rate on the Verbatim disc was (for about 8 minutes worth of digital audio)...2980. But for the same material on the cheapo TDK disc...there were only 161 C1 errors !!!
Then I realized...the Verbatim media was the "DataLife plus"; & not their audio media ("Vibe Music".)
So, my question is: What exactly are the physical & technical differences between the two (CD-R Data & Audio); & does it make a difference (as it obviously seemed to)?
Thanks,

BTW - PlexTools has the ability to check blank discs for various quality & error prone conditions...& I'll probably test the two media types myself for comparison. (But I'm still looking for some technical feedback.)
