    I want to know how you can find tshis out WITHOUT putting it in a CD Drive. Like my friend just looks at the Optical surface, and he knows wether it' been burnt or not. Is there a mark or something there?

    the burnt area is usually a little darker than the area to which data has not been written.

    Yea... if you see your cd in some light..you'll be able to see a clear dark circle, concentric with the outer rim nd the hole inside, the dark disc is basically an indication of the amount of data burnt on the cd, but its diff to distinguish b/w a completely written cd and a blank one coz a full disc has the dark layer all the way till the outer rim. So, in that case, u just gotta distinguish b/w the colour...a blank cd is lighter..................

    guys, to tell th etruth, it is hard to differentiate btn a completely burnt CD and an empty CD.... by seeing the darkness of the surface

    Atleast, I have found it difficult to do that.....

    It's not difficult , but with trained eyes , you can spot the difference between a burnt CD or an empty one.

    its very simple.....a brand new blank disc..has a dark circle which is like on the most minimum possible circumference (in the inner side ) u can think of...and as soon as it is written ..the dark circle moves out of the area..like u can see two rims /dark circles togther in a totaly blank disc...while even if the disc is slightly written(like 1-2mb) also ..the two circles get separated ..havent u guys noticed..it i have been doin this for almost 2 yrs now ..its so easy...and it is really true and works ..
