Sorry I haven't posted a blog update in a while. December has been an incredibly busy month for me.

Anyhow... I've received a lot of angry emails from some customers who received damaged CDs in the mail from us. We switched to a different type of printable blank CD-R disc for our courses, and apparently they don't hold up well in cold weather.

I tested a small batch of these way back in September and we didn't have any problems with them. When my supply of old CDs ran out, I bought a ton of these new discs. Apparently, in the cold they flake (the printed side of the CD actually flakes off). Well, this is no good since the DATA is actually stored on that printed side.

Anyhow... if you received a CD that is damaged in ANY WAY, just Contact Me via the web form and I'll send you out a new CD pronto.

Whether you're using conventional CDs or burned CD-Rs like we produce, the data is stored just under the label NOT on the "down" side. The down side is really nothing more than clear plastic to give the CD strength and shape. The data is "burned" on the back side of the CD-R label. If you don't believe me, see this article. Read More... The problem we had was that the new CD-Rs I purchased didn't stand up to the cold very well. The CD got cold and the label flaked off. I'll post some pictures of some of the CDs that people sent back to me. It's not pretty. When the label flakes off, that's all she wrote. The data is on the backside of the white label (coating). The rest of the CD is just clear plastic. Don't believe me? Crack one open and see for yourself. The reason why CDs don't work if you scratch the bottom side is because the laser has to shoot up through it. If the path of the laser is obstructed, the data can't be read. If you look at any of those home "CD fixer" kits, what they basically do is grind away and polish the bottom of the CD to remove any scratches, but the DATA is still stored right under the label.
