Quality of your CD Burner is Key
If you have a good quality CD burner to begin with there is less chance in making 'coasters.'
Plextor is the burner I chose a few years back after reading reports on its great performance with all media used overall. Quite a few salesmen commented back then they considered Plextor the top burner out, one even said "it would burn any media and would probably even burn on a postcard if inserted!" That sold me. Still use that 4 year old Plextor burner and can honestly say I haven't made a single coaster! Have used all types of media from 'brand name' to 'no-name' and they all worked flawlessly.
BTW burned a couple hundred CDs so far with 0 coasters made.
