What's the capacity of a CD?

Hi.
 I thought it was 650MB, but now i see that i'm able to burn (using MakeCD) and view properly CDs with about 703MB of data each. So, what's the true limit?

 Are there any disadvantages from filling your CD with so much data? Does it make it more prone to scratches or anything?
 I have already found one: I burnt a CD with 700MB's of jpegs and my jpg capable DVD player can't recognize it but my Amiga can. Is there anything else i should know?

Ok, thanks everyone!
 According to Piru's link, i should not fall into any problems. Perhaps i should handle the cds more carefully as

Many disc manufacturers extend a recordable disc to leave a small margin of extra groove at the outer edge.

 and i, like most ppl grab them from the outer edge.


@Effy
 That extra 200MB sounds appealing!


@AJS
 No, it has to do with the size of the CD. It will recognize it if it's 650MB or less.


@Vincent
 Yes. I see now where this 730MB comes from.

 My signature says that i'm using a classic Amiga but i don't see how's this make the 700MB more sufficient for me. :-P
