i think its kinda shitty.. why even make these? they offer very little extra storage capacity compared to the original. especially now that dual layer discs are about to get hot..

80min cd-r's VS 74min cd-r's was totally worth it..

this = crap

they could only squeeze another 150mb extra , why bother , probably costs them millions to research it aswell , lol

The fact was that 650mb was the 'standard' for cd-r's was amazingly stupid. They did that basicly to compensate for absolute crap media, since the very bad stuff would work very poorly at the edges. Since then they've really improved media (even the unbranded cheap stuff), but as far as I know they didn't compensate for bad media as much when they created DVD. The main reason was because any dual-layer disc would be required to have very good read characteristics at the very edge of the disc when it switched to the second layer. Also, fitting more before data that crossover point (despite it being single-layered media) isn't as easy to due as it was with cd-r's.

On a normal [sized] blank they fit over 33% more onto cd-r's (74min vs 99min), but I think that big of a jump isn't possible with dvd+/-r media.

And the first writeable CD was 63 min/530 mb... They did not research anything, but changed some physical parameters. Also well, the extra capacity on DVD already existed, you can OVERburn your DVD+ disks with a decent burner. (+sw that allows it) 4.6GB (talking about sizes, the normal DVD-R can hold 4.38GB aka 4.7GiB) on a Verbatim DVD+R is possible with a Plextor writer...

If it cost 1cent more than the 4.7gb i would buy it.
