Hi, I was wondering if anyone knew of a list of safe markers to use for labeling cds/dvds? I have heard that certain types will leak thru the top layer and destroy the data on the disc in doing so after a period of time. The only markers I have used to label with are: Staedtler Lumocolor 317 Sharpie Ultra Fine Point If there is no list, does anyone know if these markers are OK for labeling cds/dvds?
