Any CD's bigger than 700mb?

Factual Questions
1

I just had a video project I wanted to put onto CD, it’s 717megs in total and I don’t really want to cut or crop anything out nor can I because I just finished school. The biggest CD’s I’ve got are 700megs a pop. Would making it a zip file reduce the size? Am I hopeless?

They make 800 MB CD-Rs. Here, for example.

well i believe you can get 900 megabyte disks but they are nonstandard meaning they will not work in most drives. there is also a burner out that can write about 1.5 gigabytes to a standard 700 megabyte disk. however this is agian makes nonstandard disks. most cd-roms will not be able to read them. however a good chunk of dvd roms will be able too.
what format is the video project in? formats like divx and ogg are compressed about as far as they are going to go. if they are not already in a one of the 2 converting it to them should reduce it’s size by third with out much if any loss in quality.

80 minutes is the maximum possible length for a Compact Disc according to the ISO specifications. 80 minutes is 700MB of data in Mode 1, 800MB in Mode 2. This length is achieved by taking the ISO standard length, 74 minutes, and then stretching the specs as far as you can go while still keeping the disc technically in spec, including shortest possibly pit and land lengths, tightest tracks, etc. In your case, your best option is probably to overburn. Overburning will make the disc non-ISO compliant, but will generally work in most drives if you don’t try to overburn too much. 90 and 100-minute discs you see for sale are simply pretested for good overburning characteristics. The problems of heavy overburning are still there, including incompatibility with many drives depending on how much you overburn. Just because the disk is marked 900MB capacity doesn’t mean you’ll be able to burn NEARLY that much, or that it can be ready anywhere even if you can fill it. Alternatively, you can try using something like WinRAR to shave the file down as much as possible, or you could recompress using something like DivX.

Note that VCDs and SVCDs are burned in Mode 2, thus giving you 800MB of capacity per 80 minute disc. You could try just burning your video file in Mode 2, but you will lose all bit-accurate error correction, meaning that even a minor scratch will render the disc unreadable.

I saw burner the other day that said it could burn 1GB on a CDR.

6

Plextor makes burners that can burn 1GB to a disc using a proprietary “140% write mode.” Such discs can only be read in the drive that wrote them (or another drive of the same model), making them rather pointless.

7

I wouldn’t call that pointless for archiving purposes. But for distribution to other machines, yes, quite pointless.

8

Part of the advantage of archiving is future readability. If in a year or so, when your plextor has died, you want to read the data, you’re screwed. Better to just go for a DVD burner if storage is that important to you.

I’ll agree that eventually your stored data will be worthless, but a year seems a bit short. I have a backup 1/4" tape that I’ve had for nearly 5 years now, but iof the need should arise, I can still find a drive for it on eBay or someplace similar.

      • How much data you can get on any CD-R depends on a number of factors, a few being the CD-writer you are using, the CD-R blanks, and the type of data. How’s that for a non-answer?
