Isn't it supposed to be one long, spiral groove? Well, with pits in it, of course.

WTF???? LOL!

Hahaha, what!

I mean CDs/DVDs have one long spiral of "lands" and "pits", as they're called in the trade.

I guess I didn't quite understand his question.

It's my last question on my sheet, I've checked wikipedia several times with different keywords. And there is no way i'm going to be able to count them on the disk. If I can find it on wikipedia, what keywords would I use?

 

[Meithan]
