My biggest fear has been damaging/scratching a Mosaic disc.
CD blanks are cheap, any office supply store sells them in cases of 50-100 with rebates so they cost almost nothing versus injuring a Mosaic disc. I copied a few hundred of my CDs including many Mosaics to have a chunk of my collection at work because I can listen all day 40 hours /week. My wife bought me an Ipod last October, now I can carry 80 cd's worth of music to work in a tiny little box that I can plug into my tuner and hit the "shuffle" button, randomizing my listening to tracks of Chaloff, Konitz/Tristano, Quebec, Desmond ,Blakey, Morgan, Mobley, Jacquet, Byrd/Adams, etc...
