Yes, there are 90 and 99-min CD-Rs, but they are a bit.. dodgy, to say the least. Most later-developed (more modern) CD-RW drives will support burning up to ~90min, and some even more. However, you may have to burn slower (at a CLV speed),and disable burn-proof, in order to burn past 90min. Also, those CDs wind the "spiral" of the CD much tighter, and so are rather out of spec. Many CD players may have trouble reading them. All-in-all, I don't personally think any CD-Rs longer than 80min are worth it. I've even had playback problems with 80min CD-Rs on some players too, so I keep a stash of 74min CD-Rs around too. (Those are getting *very* hard to find, too. )
