It's also a great way to assure that the disc won't be readable later on. The damage won't happen today, or even next month, but at some point the ink will leach into the reflective layer of the disc and it'll be the end of your data.
Now, we're not saying you can't label your discs. But you do have to be careful of the kind of writing instrument you use to do so. In order to understand why certain markers and pens can harm your CD-R s and DVD s, we first need a basic lesson on the physical properties that make up the disc:.
The plastic is there to carry the data layer - the shiny metal you can see when you look at the bottom of a disc. Most people know that it is very important to keep the bottom of your discs clean and scratch free. Scratches, fingerprints, and other debris can stop the laser from reading the data.
However, most people don't realize that the tops of discs are just as prone to damage as the bottom - if not more so! Although you can physically see the shiny data layer from the bottom of a CD-R, it is actually applied to the TOP side of the disc, just under the label. On some CD-Rs, the data layer is under nothing but a thin layer of lacquer.
Damage to the top of the disc can destroy the data all together. However, this does not make it immune to damage. Location: Winnipeg, Manitoba, Canada. I've heard the same thing so I picked up a CD-R marker labeled 'Archival water based permanent ink' to use instead of a Sharpie.

It's better to use a water-based Sharpie. Do NOT use papar labels! Grant , Apr 22, Location: Montreal. Agreed, no problem whatsoever with sharpies. Location: USA. Getting harder and harder to find audiophile papar. DjBryan , Apr 22, Location: San Luis Obispo California. I'd be more concerned about the stability of the dye within the disc than any effect of the sharpie.
I do suspect the disc would become unreadable a very, very long time before the sharpie eats its way through the plastic coating but that's so much armchair commentary. What I can say confirms Grant's reply. I've been using a sharpie for several years on my data CDRs and have not seen a trace of any potential problem from it.
Go water based if concerned. Just don't use anything that is abrasive, hard or that contributes any weight such as paper labels. You may want to look up Staedtler Lumocolor Permanent markers. I read that the chemicals in a sharpie marker, when written on the metallic surface of a CDR could cause a chemical reaction that will cause an explosion!!!!!

All times are GMT I got bunch of these from meritline. Now, they are silver at the top and purple in the bottom, so i am wondering if its ok to use a Redisharp marker or a sharpie to write on top silver side of these.
Would that be alright? Home News Reviews. Okay to write on discs with a marker? Blank Media. Those 3 are the main types one will encounter. There are other brands on the market now, like Memorex, etc.
