Self-Healing Disc!

L0, which holds more data is on "the outside". It is burned first then the laser refocuses on L1 (inside) and burns.

hmmmm, pm

nevermind, looked at picture rightside up, doesn't make any sense tho

[TNT]

It seems to me it would be easier to burn inside out. Then you wouldn't have to burn through a layer you just burned. But then, what do I know.

[Chewy]

me neither

edit: got it, trying to burn deep hazes the shallow layer, but burning shallow first
locks the phase change dye. it's a wonder it works at all

Facinating!

Just a question about that site:

You can pack up to 12 CDs or 5,902 floppy disks’ worth of information onto a single dual layer DVD disc.

Do you have to set a layer break when putting data on a DL disc? If so how? And if not, can you put one huge, say, 5 GB file on it, even though it will span layers?

TNT,
in this otherwise excellent review of a burner par-excellence, notice the reviewer uses a dual-layer DVD+R from RIDATA for speed tests, but
doesn't even review this media burned in the quality section.
Don't feel alone.

Arighty!

Um blutach... that guide is for video. There are no IFOs and VOBs in data DVDs.

[blutach]

Then use your burning prog and just set LB manually.

OT: What's this got to do with DV?

[drfsupercenter]

So... you need a LB for data DVD's then? How do you set it, and what happens if it is just one huge file (UDF mode) - can u break in the middle of a file?
Not that I would do this, but always nice to know
