Annals of Archiving: DVD flavors

So you’ve been wondering while you’re backing up your photographs (ha!) which kind of DVDs you should really be feeding your PowerBook…

Thanks to an entry in the blog “Ad Terras Per Aspera”, I learned more than science considered possible to know about blank DVDs. My disc-fountain overfloweth.

In essence – DVD+R is better than DVD-R:

DVD+R uses a superior ‘wobble’ laser tracking system, a far better error correction method, and the media quality itself is typically higher.

unless you’re burning video DVDs for playback in your parents’ DVD player, which is a mildly stinkier kettle of fish. (Wobble laser tracking system. I’d like one Wobble Laser to go, please.)

DVD+RW or DVD-RW both tend to let your data quietly decay away.

Dual layer (DVD+R DL) ain’t worth buying.

And the brand “Taiyo Yuden” is apparently worth hunting down, though I have to confess I’m gonna stick with burning two cheap discs instead.

This is all assuming that your burner enjoys all flavors of DVDs, which some old ones don’t.
