Dual Layer DVD+R Developed

Lucretian writes "And they said it couldn't be done... It appears that Philips has found a way to burn a dual layered DVD+R. Unlike other dual layered disks that have been developed, this one is also designed to be backwards compatible with current DVD players. Phillips will be demonstrating this new technology at CEATEC this coming week at the DVD+RW alliance booth. The DVDs will hold 8.5GB of data (4 hours of video) and are set to be released as soon as next year."

Re:dual layer double sided?

Those are stamped discs, not burned discs. Stamped discs are made using a radically different process where the pits and grooves on a DVD are actually built up in layers and stamped onto the backbone of the disc (the plastic part). Stamped dual-layer DVDs have existed for some time now; Phillips is saying that they invented burnable dual-layer DVDs.

One recommendation for the future is to make use of the PAR/PAR2 utilties. (I personally use QuickPAR v0.7)

Basically, you create 'parity' files that you store on the DVD/CD along with the source files. Then, if any of the source files become corrupted, QuickPAR should be able to reconstruct the broken bits.

The amount of redundancy is up to you... 10% is normal, 20% might be worthwhile. (So to store 4Gb with 10% redundancy, you'll need 4.4Gb of space.)
