I never quite understood why “you’re not supposed to” use standard markers on a CD or DVD (perhaps the tip can scratch the surface?), but I remember I had at one time bought a “special” marker for such a purpose. Yet, today I went to two Staples looking for such an approved writing device. You can find them online but, according to the helpful sales clerk, they no longer brand markers for such a task and he recommended a fine-tip Sharpie. I wonder why. Was this just marketing hype to begin with?
Well, what did catch my eye was the $80 Casio disc printer situated by the shelves of optical media. Yeah, who needs a Sharpie?
