Ah, I had not heard about that problem - but it make sense.
In one of the video magazines I subscribe to there was an article
that was very emphatic about not using "Sharpie" (or other permanent
marking pens) because the acid based inks would erode the top surface
and cause data loss. However, the test conditions involved 60C
temperatures for 100 hours... Their recommendation was to use the
inkjet printable media and an inkjet printer because the inks are
water based.
I use the permanent marker pens and my philosophy is before the time
the data is in danger of being lost I will have migrated the data
to the next generation of media. In a couple years the "Blue-Ray"
(or comparable) media/recorders will be available and will hold much
more data - so I will merge 5 or 6 DVDs onto a single disc in the
future. Until that time I use the "Sharpie" pens and store the DVDs
away from light and heat.
Cheers,
Steven Schultz
