The State of Recordable DVD's

Posted by michael on from the shiny-things dept.

An anonymous reader writes: "The Tech Report has a review of two DVD writers, one from each of the two competing standards (DVD-R and -RW and DVD+RW). In addition to testing the performance of each drive, they also test a bunch of DVD players and DVD-ROM drives to see how well they read the different types of media."

    Digital tapes do wear, but the error correction helps mask it. If you ever actually work in production, you rarely re-use digital tapes even when they cost $100+ per unit. Any engineer will tell you its a bad idea to re-use them for storing any master. When they do wear out, you start to notice concealment rates skyrocket on the devices that let you view the graphs. If a professional production house were to send that out to a client as a master, that would be a coffin nail.

    I don't know what DVD player you have, but my DVD-RAM media won't work anywhere else

    My DVD-RAM uses a square plastic caddy like old CDROM drives. The difference is that every DVD-RAM media has it's own caddie and the caddie is supposed to be permenant... it contains the read-write tab like floppy disks have, etc.

    You can sorta get around this...

    Take a DVD RAM cartridge and *carefully* crack it open. You can take out the DVD disc and if you wrote a disc with a digital movie some DVD set tops will work with it. There are not many though (more sets will read the DVD+RW or -RW than a cracked DVD-RAM). This is probably why you don't see them... you can't exactly put the disc+cartridge in a DVD player and most people then turn away from them, and cracked discs don't ever work real well. And as the article said, mor ppl are expected to use them in set tops than for data

    I don't know if you can put a standard DVD-/+R(W) in the cartridge and use it. If you look at the DVD-RAM disc, the coding is much different in appearence from the other standard disc's

    I have a Creative DVD-RAM, which I have been pretty pissed at. Looking on the data side, of the backups I have done, I have always had files lost during the backup write. The only advantage it had was I got it pretty cheap (about $250 2 years ago)
