9.4 gig Media?

[nutt318]

Is 9.4 media ever going to come out on a single side. If it does I think it would be almost to easy. But im just wondering if anyone knows anything about it.

Thanks

Don't hold your breath!

I'd put a quid on dual layer +/- disks not being released.

Why?

Do a search for blue ray!!!

bearly any merchant carrie 9.4GB they are all out of stock, or crappy princo..

We're talking single sided here!

I don't see the point of double sided. They're a lot more expensive & if you have to turn it over, you may as well put in another disk.

There are no, and will be no, single sided 9.4GB DVD-R or DVD+R discs. Burning multible layers is not compatible with current recordable technology. Do a forum search... this comes up all the time even though it has been explained in extreme detail before.

My guess is that they will come out w/ multi layer burners and multi layer media at the same time.

To say that it wont come out is being a bit close minded.

Ok, but it's fair to say it's highly unlikely there will be dual layer due to the complex technical issues (commercial dual layer are just two burned layers stuck together), and due to teh fact that none of the major manufacturers are working on anything. They are all working on some flavor of blue ray or blue laser technology.

You will see DVD2 before you see Dual layer DVDR. It's all in the economics of the engineering. It's easier to get 4x-10x the density on the disk than it is to go with dual layer. A LOT cheaper too, single laser instead of dual/laser or a complex optical system.

The problem comes from trying to write the second layer without frying the data in the first layer. You have to use a focused beam, or multiple beams. This means you are diffuse in the first layer, but concentrated in teh second layer. Needless to say this is difficult. And Impossible to do for $300 US a unit. Now if you want to pay around $5000/unit (much like the original CDRW 1x drives) and Who knows how much for media ($20 US?) someone might engineer a unit, but it would be non-standard with everything. I bet you can't find a DVD player that will play it. It would be like the 99 Minute CDRW, a proprietary sytem.

Economics won't allow it, but economics will make the next-gen of DVD's at least 4x as big( if the MPAA doesn't kill it like they tried to do with VCR's and Digital Tape(digital tape was successfully delayed in the US for over 15 years) and others).

No. There are two contexts to read here:
1. 'Will 9.4GB media ever be available that I can burn on my current burner?' Absolutely not - anyone who thinks this will happen doesn't understand how burning works. This is, of course, what a lot of people want when they ask about 9.4 discs (but most ask it casually, like when they ask if they can burn DVDs on their CD burner).

2. 'Will they ever make dual layer recordable media and burners to burn them?' It may be technically possible, but as has been pointed out it won't happen (the odds are so low it's almost the same as zero). It's so technically different than single layer burning (and different from dual-layer pressing) that a company would have to invest a lot of money, and there's little chance of that when the next gen technology is already in the pipelines.

Same-gen technology is a short-term investment, and not worthwhile if it costs too much. Also keep in mind that increasing capacity by two-fold would not raise demand or value enough to justify the huge price increase. Kids won't buy a $20 blank to save $20 for buying a movie (and that's why most people ask).

Are you sure about that? I thought commercial DVDs were pressed like commercial CDRs. I can't believe they are burned.

[sammie]

yeah, sorry just being a bit sloppy there. Point is they are made separately and sandwiched together not burnt in two separate layers.
