Hej Alle...

Nu har de tryllet 99 min. ud af en CD.

Er der nogen der ved hvordan dette kan lade sig gøre ? De første år var det 74 min. og så er der ellers blevet lagt nogle minutter på år efter år. På et tidspunkt må der da rammes en grænse ? "Sporene" må da blive for små, til at en rød laser kan få noget brugbart ud af det, eller? Er det i virkeligeheden CD´ens diameter og laserens fysiske arbejdsradius, der sætter grænsen?

Kan en alm. CD-spille læser disse 99 min. skiver

Subject: [3-8-2] How well do 90-minute and 99-minute CD-R blanks work?
(2002/11/26)

Small quantities of 90-minute and 99-minute blanks have appeared, but since their introduction in late 2000 they haven't become as commonplace as other lengths. Indications are that many recorders and some software don't really work with the longer discs.

The discs have capacity of roughly 791MB (90 min) and 870MB (99 min). However, all the capacity in the world won't help you if you can't read the disc back. If you're interested in larger but incompatible discs, and don't want to pay the premium imposed by DVD-R, read about DD-R/DD-RW in section (2-37) and ML in section (2-39).

CD time stamps are two digits (binary coded decimal, in case you were wondering), so exceeding 99 minutes isn't possible. You could, in theory, declare there to be 99 seconds in a minute and 99 sectors per second, but that would break just about everything that tried to read one. The limits of the specifications are being pushed at 80 minutes and even harder at 90, so don't expect much more out of CD-R. Some knowledgeable individuals have stated that the longest possible CD-R is 79 minutes, 59 seconds, 74 blocks long, because of the way that the last possible start time of the lead-out is encoded, but you can use "overburning" (discussed in the next section) to write past that point.

See http://www.mmore.com/download/Technical_write-up-MMORE_90_min.pdf for a tutorial on burning 90-minute discs with Nero. In short: make sure your drive supports overburning, set "Enable overburn" in the "Expert features" tab of the preferences, ignore the warnings, and cross your fingers. Always verify the disc afterward.
