cdr's over 700mb 4

[JAKM]

I recently bought some 99min cdr's but find that my burner only reads them as 702mb. I heard somewhere sometime that some cd burners don't read cdrs higher than a certain amount of memory and am wondering if this is the case here?

Have I been bamboozeled or do I need to find a burner that can read the proper memory capability? Any advice would be helpful,
Thank you

Standard music cd's are 74 minute, 650MB. Any working burner can read/write these. Next are 80 minute, 700MB cd's. Almost every relatively new burner can read and write to these. I haven't really been paying attention lately, but I've never heard of 99 minute (somewhere around 850MB). There are 1.3GB cdr's that are 'double density' (650 X 2), but they require a special drive.

I poked around at a couple of online stores and didn't find any such creature. I suspect that you've been bamboozeled.

Do a Google search on 99 minute CDRs. They have been out a few years now. This from Google:

" To make a 90 minute or above CDR, you have to use NERO 5.5.4.0 or above that supports overburning. Set maximum CD length to 99 minutes, you also have to burn under "Disc at Once" mode, and at 8x speed or under. Also, consult your CD Writer manufacturer on 99 minute overburning. Not compatible with all CD-R drives!"

Jim,
I don't believe the CD's themselves are sold with "99 minutes" printed on their labels or packaging. The google search you found is general knowledge that you can cram 99 minutes into an 80 minute CDR by the process of overburning. Just like that excerpt states, not every burner can overburn. I'll also add that if you are able to overburn, there's also no guarantee that every CDROM/DVD-ROM drive will be able to read them.

Now, it is true that some 80-minute CDR's work better with overburning than others. However, I myself have never seen a CD being sold with a higher capacity that doesn't require overburning. If there are 90 or 99 minute blank CDR's being sold out there, double-check their packaging. I'm quite confident they'll state that you need to overburn to accomplish this. That is not the same as an 80 minute CD that doesn't need to cheat!

This info was in the link wee provided:

"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."

This subject has bee discussed before in this forum, but I couldn't find the thread. Plextor used to have info on this on their web site. They didn't recommend using those CDRs on their burners.
Yes, those 90 and 99 min. CDRs do exit, but they may or may not work and can even damage some burners and won't play in some players.

Here is some info from Plextor:

"Which Plextor drives support overburning?

The Plextor PX-W4824TA (ATAPI) and PX-W4824TU (USB) support overburning, or the ability to record beyond the maximum storage capacity set by the Orange Book standard, up to 94 minutes, 55 seconds.

In order to utilize overburning, the recording application must support that function. The application needs to be set to enable overburn, must be set to DAO (disc at once), and the session must be finalized. Overburning cannot be written in a multi-session environment.

The selected media must be either 90 minute or 99 minute in rated capacity.

The majority of CD-ROM/DVD-ROM drives, and virtually all home or car CD/DVD players and portable CD or MP3 players, will not read 90 or 99 minutes discs. You generally have to play them on the recorder that created them. Most of the drives will not read the overburned discs at all. If they do read the discs, they may only read up to 80 minutes of audio. Overburning is not supported by any recording standard. It is a response to market demand for increased recording capacity and players do not yet support this feature. "

Jim,
Thanks, but I already reviewed the link from weegeordie. In both of your posts above, you just reiterated that overburning is required to exceed 80 minutes. That was my point. There is no such disk out there over 80 minutes (700MB) that will work without your CD-writer overburning the data on CD.

Thanks again, Jim! Perhaps I'm a bit behind the times, but can you show me a burner that can write more than 700MB without overburning?

Plextor had an article about these CDRs sometime back, but I can't find it. I don't mean to beat a dead horse, but these 90 and 99 minute CDRs are made different someway. They are more dense and use more area out to the edge. You are right in saying you have to have NERO and over burn to be able to fill up the disk. Not all burners will do it and not all software will work. And after you make the disk most CD players won't play it all, so it's probably a waste of time and money to fool with these things. My only point was that yes these special disks do exist and yes you have to use burning software that will over burn. I agree with you. There may be some professional burners that work fine, I don't know. Jim

Thanx alot for the help, we have the newest version of nero so I hope to use overburning this weekend. I havent been able to test it out yet due to a problem which I mention in another thread. I'll post another message when I do try it out. Thanx again for your messages.

I use 99 minute CDR's regularly. I've also used some 90 minute ones, but why bother with those since they're basically the same cost? Nero (in it's current state) only reads the 99 minute CDR's as 702MB, however, when it says "Do you want to allow overburning", click YES, and you can burn approx. 872MB of data onto the disc. This is equivilent to about 98:50 of music/video.

Many Many sites sell the high capacity CDR's and almost every drive supports them, but I only know of Nero and a couple other generic programs that actually can support overburn. Roxio DVD CD Creator 6 supposedly overburns pretty well also, but I haven't tried it.

Take my word on this though, 99 minute CD's work perfectly.
