long time that i want to know about this.
see i got an asus 5224a writer, and i cant check c1 and c2 errors with this. Neither have a lite o plextor near to chek'em out.
So i have found my own way to check quality by testing the discs on an old cdplayer. this player has lots of troubles reading bad quality discs (like cmc's). so far i tried those manufactured by ACER MEDIA (labeled as BENQ) and they work great with the stereo.
but i have found that in alll discs no matter what brand they are (cmc, verbatim, plasmon, etc) the burned surface doesnt look the same way if they are burned beeween 16X and 24X.
If the disc is buned under 16X the burned surface looks weak (is harder to compare the burned and unburned area)
but if it's burned over 24X the surface looks "stronger" and it differs a lot with the unburned area.
check thi pics.it an example of a multisession disc.


MY QUESTION IS: does it makes any difference if the burnt area looks stronger or weaker to the eyes?
Recording over 24X makes better quality discs?
