ha!?!?!?! your friend is pulling you leg , no way... you can tell him he is a lier. look at a cd-r you can see right through it (if the cover isn't thick) it has just a few thin layers in which to store data on, look at DVD+R it's dark purple, there are many layers on this one, aka- more layers more space. "unlock it" - and a cd+rw is the same (rewritable) so you can tell your friend he is wrong. now it can hold over 700mb if the file is compressed, but at max only 900mb, no where near 4.7gb

^^ Theres also overburn for burners that support it, but even then you can only get around 750mb max safely on a CD. I remember some company a while ago released a burner that could fit 1.4gb on a CD-R/W but Ive never seen one available for purchase.

1.4 gigs, perhaps a dual layer cd-r, kinda like a DL-DVD+R/-R, that would make sense, i have never heard of it though, i'm taking uncompressed,

google on overburn popped this up:

That article makes it look like a little bit of additional space is possible.

810MB on a cdr.. and only if used as SVCD. It has nothing to do with layers as previously wrongly stated.. It is down to the data density. The spacing of the pits and spaces in the pre-printed spiral track. There is no such thing as a dual layer CD.. and never will be. The specifications were fixed a very long time ago. DVD is different because the specs allowed for multi layer disks from the outset.
As with any media there is always a little bit left over for manufacturing tolerances and hardware variations. Some devices allow accessing this, some do not. I can put 1.77MB on a standard 3 1/2" floppy, and do regularly.

Overburning on any cd or dvd is a little risky.. you are pushing the laser beyond it's design end stops, and void any warranty by doing so.. At your own risk eh?
