what is OVER burning CD-R's?

[Beautiful Alone]

care to explain?

[biggantdogg]

Burning video, sound, and or data past the the limit of the disc.
(ex 80min 700mb disc you can over burn to 800mb when burning VCD since it's time dependent.)

so..are there any disadvantage of over burning? so..lets say i over burned a VCD to 800MB, so will the 100mb over burn VCD still be readable on my dvd player?

a VCD (or SVCD) file being 800 MB is NOT overburning...does nero tell you the file is 92 minutes after you have added it? No, it says it is 80...

No, overburning is what I do...putting an 804-809 MB VCD/SVCD file on a CD...or burning 704 MB of (non-VCD/SVCD) data on a disc.

here's what Nero says about over burning.

Warning: Since normal CD-R are not design for this amout of date, there might be errors at the end of the cd. you could alos possibly damage your CD recorder.

If you overburn too much it will damage your disc at the end such as your movie might not end properly and jerking, out of sync around a few last minutes of your disc.

But for VCD, SVCD and AUDIO we count it as minute burnt, So if your mpeg file is 790 MB, when it's burnt burnning software will calculate as minute (10MB/1min) so you file is around 79 mins which is not over burn.

I've never over burn for DATA but over burn a lot of VCD, SVCD. The maximum I have done is 81-82 mins which is around 820MB

@Beautiful Alone- well, you just have to make sure you buy decent media and have a decent drive. Honestly, it doesn't gain you anything...I do it because I can, no other reason. Every once in a while it can come in REAL handy, though...

The cd-r i have saids 80min-700mb. but if i make a 80min vcd, which is 800mb, would'nt that be over the capacity of a 700mb cd-r? so..that would be over burned, right?

another reason for overburning is when you use the 99min. CD-R's, to burn to 98-99min. at around 980 to 1000MB on one of these CD-R's you must turn on the overburn on NERO or it won't go past 796MB or 80min. and you have wasted 200MB or about another 18-19min. on one of these CD-R's, providing your burner can overburn these discs and the DVD player you have will play them back. I play it safe and put no more than 960MB or about 96min. on one of these discs, avoids any errors that may crop up.

The term overburning is generally applied to mean burning more data onto the disk that what it is rated at. In practice this is basically true but the actual term overburning refers to a specific process. All cdr/w's have a 4 second space reserved for the TOC. Overburning is the process of burning through this 4 sec (40MB's) space that is supposed to be off limits. As long as you don't overburn too much there will still be room for the TOC and the disk should work fine, though certain devices may have difficulty reading data burnt past this point because the further towards the outer rim the data is stored, the faster the disk has to spin.

So technically the most you can overburn is about 40MB's, but depending on the media this varies.

As for 90 and 99 min cdrs. Yes you must enable overburning in Nero but this does not mean you are actually overburning anything. You are not burning through this space reserved for the TOC and you are not burning more data than what the media is rated at. So why does Nero force you to enable overburning? Simple, 90 and 99 min media are not standardized yet so as far as nero is concerned they don't exist. Nero assumes that to fit 90+ min onto any existing media you would have to overburn, but you don't.

I don't necessarily agree with the details adam, but the gist is correct...

The space for the TOC (which is BEFORE track 1) is always reserved and you can't ever burn "user data" into this area. Perhaps you are talking about the "lead out" section?

Each CD-R disc will tell the drive the number of sectors for user data it contains. Often, it will actually contain more. When you burn a disc in EXCESS of the rated number of sectors, you are overburning.

It is HIGHLY unlikely that overburning will damage your drive. Of course, you are pushing your drive beyond its limits so it is a "possibility", but in the many years since CD burners have come out, I have never heard of one story of this being the case. I wouldn't worry about this...

The "sectors" beyond the rated section could theorectically be of poorer quality than the rest of your disc, so data integrity may be an issue. This is unlikely however. Usually, the "skippy" video at the end of discs have nothing to do with data integrity at all -- rather, it is a media compatibility issue with the playback device.

If you overburn too much, however, you may run out of sectors altogether before all your data is burnt. If this is the case, your data will get truncated. Bad news for a data CD, but for an audio CD or VCD, it will just mean that the very end of your video will be missing.

However, if this occurs and you are burning in TAO (track at once mode), then your disc becomes a coaster. This is as the TOC of the CD is written last in TAO mode (but it is still written on the inner margins), after all the tracks have finished recording. If you run out of sectors when overburning, your drive will give an error and the burning process will stop. Without the TOC written, your disc is unaccessable.

This is one of the reasons you should burn in DAO mode when overburning!! In DAO mode, the TOC is written first so even if there is an error with burning (e.g., running out of sectors in overburning), the data that is written on the disc will generally work.

Regards.
