Re: [ARSCLIST] CD-ROM marking pens

[Jerome Hartke <jhartke@xxxxxxxxxxxx>]

Solvent-based inks, such as used in the Sharpie, can penetrate the
protective layer on the label surface of CD discs. The formulation of this
layer varies; some being more resistant to solvents than others. I am glad
that you have been lucky, but do not recommend use of such pens on discs
that are not easily replaceable.
