Overburn

[Baldrick]

According to the official standards, a cd (and a cd-r disc as well) should have a capacity of 650MB or 700MB of data, or an equivalent of 74 minutes or 80 minutes of audio.

As the laser beam in a cd recorder writes on cd-r media, it travels from the center of the disc towards its edge. Before the physical edge of the cd, there is an already set limit to prevent the laser beam writing beyond that, so that the physical edge of the cd's writable surface will never be met.

This means that there exists a security zone at the edge of the cd-r media. If we could write into that security zone, we could gain in capacity, since we would be able to write more data on the cd. This is called overburning.

Has anyone had any experience with overburn, and knows the capacity for a certain brand of media? Something like TDK, or Verbatim, or Memorex, etc.? I think that would be a handy thing for everyone to know. I understand these would not be exact, but just a basic guideline for each brand.

My experience with making vcd discs on 80min cdr, just about all ive tried go to about 82min, 23 sec. Anything over that is a no go. There is a list out on the web somewhere as Ive seen it before. Of course you could just use a software proggy to tell ya all the junk about the media overburn/dye type etc.
mt rainier maybe

I've never tried to overburn, but when I use a TDK 80 minute CD, Nero says I've got approximately 82 minutes available. I've heard of some people getting up to 84 minutes on some 80 minute CD's.

Also The software i was thinking of was FUERIO not Mt rainier, sorry.
Anyway, those are approx times, but like I said before, Ive burned using almost every name disc and most are at 82min.20sec. chepos same as expen ones.

JID10T,
If you're a Nero owner, it's a free upgrade/download, I think 5.0 up.
