Memory-Tech and Toshiba announce new three-layer TWIN format

This new twin 3 layer format allows for a combination between the layers on a single side..with two layers supporting HD DVD, and one supporting DVD, or vice versa. They can support 8.5GB of standard DVD content on two layers, plus 15 GB of HD DVD content on the third layer. DVD content can be played back on a standard DVD player, while HD DVD players can play back both formats. Sounds confusing, just hope the new players are not.

Viewing the article, it looks like the industry can keep one side for artwork and the other for data... but wait this is not a done deal. "Toshiba will propose the new format to the DVD Forum, and plan to develop a reliable disc manufacturing process together", brings to question the basis for HD-DVD and low cost conversion.

My local BB is offering HD-DVD's with standard DVD9 on one side and HD-DVD on the other... isn't that a better solution to TWIN disks?

The double-sided disc is the easiest solution using existing technology, but ultimately the 3-layer is better for the market if they can hit the price point, as it allows artwork to be placed on the disc and the disc goes into any player, HD or SD, the same way, with the art side up.

The double-sided discs are usually two discs bonded back-to-back, so the 3-layer has the potential to be cheaper to produce as it uses less material and has less processing steps.

The solution in the above link is really 2-layer (HD DVD and BD on the same side), with a plan to bond a conventional DVD to the other side. Since there still seems to be some yield trouble getting higher density Blu-Ray discs, I'm not sure that bodes well for that solution, but the interesting thing is here we have a studio which is obviously not happy with having to produce multiple formats of the same movie and has developed a technical solution to overcome the roadblock to combo players via an end run.

HAH!!!!

I hate to be "an old I told you so".

Actually I love it.

This is what I said last January if anyone out there is anal enough to recall my obscure rantings. For those of you who can't, I'll say it again.

.......FORMAT IS NOT AN ISSUE. BD and HD-DVD can and will co-exist.

You heard it here first.

You may quote me on this if you wish.

Thank you and good night.
