So why pay thousand of dollars on hidef players knowing that the players will enevitably be soon replaced :p by energy efficient and longer lasting diode drives ..

Will this trigger another wait and see scenario that would slow down sales the already low sales figure of expesive hidef players :p

What does it say to the current diode makers? Will they need modification to produce this improve diodes? What would the cost be like?

The nonpolar blue-violet laser diodes have numerous commercial applications, including high-density optical data storage for high definition displays and video, optical sensing, and medical applications. Because of the shorter wavelength of emission in these devices, they can accommodate higher densities of optical storage than conventional red-laser based systems.

Said Nakamura: "Our initial results of the first violet nonpolar laser diodes with a low threshold current density demonstrate a high possibility that current c-plane violet laser diodes used for HD-DVD and Blue Ray DVD could soon be replaced with nonpolar violet laser diodes, which require lower operating power and have longer lifetimes."

Hmm i wasn;t aware of any HDDVD players sellign for thousands of dollars ;) I'd happily predict 18-24 months until this see's it's way into consumer goods at retail.

How soon ? Do they have plants that can produce Millions of diodes ? How long will it take to setup such a plant ?

Excellent - more power for my double-stacked RS1 projectors! :)

he said thousand (singular) of dollars, as in "$1,000-ish" which is true if you consider the AX2 or any BD player :p

Longer life is really a non-issue. The current laser diodes have a MTBF of 60,000 hours. If your average movie was two hours, you could watch 30,000 movies before one failed. If you watched two movies per day, that is 41 years before diode failure.

Why do you need longer life again? Even if the diode was running 24/7 for some unknown reason (it wouldn't even do this gaming on a PS3), it would last for almost 7 years. Again, why the need for longer life?

Lower power might be a slight advantage, but only ever so slight.

Lifetime and power usage aren't really a big deal for current HD disc applications. The key would be a process that generates far better YIELDS to drastically lower the cost of the diodes.

But, it's a research announcement. So, expect a minimum of 3-4 years for the product to be industrialized. It can't have much effect on this generation.

MTBF means nothing (from my personal experience). Other than my DVD-A300 (Panasonic, March 1997, still in use today) every single one of my DVD player died within a the first 13 months of usage.

Get back to me in 7 years and let me know how many original PS3s are still working.

What is more importand is the drop of light output over time.
Below a certain level the optical sensor will fail to read the pits correctly.

I suspect this could be more of an issue for BR than for HDDVD.
Low reflectivity of the HD layers, higher pit density combined with the near to surface focussing yielding an even lower light level return to the optical sensor.

A longer useable led lifetime can't hurt.

a lot more than original xbox 360's still running after 1 year, lol!

My experience is the opposite I guess. I've never had a DVD or CD player fail. I have decade equipment still in use. My G1 Sony is even used in my wood working shop and keeps a healthy layer of sawdust all over it, and it still works without a hitch. My only optical failure was with a Plextor DVD-R in my PC which failed after 6 months (it would read but not write).

MTBF is the only measure of life for a mass produced electronic device. If this new diode is claiming a longer "life", then it is simply claiming a MTBF that is greater than current diodes. But since current diodes should take you to at least G7 players, life is irrelevant.

here's hoping that the new diode will make my optical readers last at least 2 years :)

Is this any different from any other evolution in technology? No. Should I have waited for LED backlit DLPs before buying my traditional bulb one last year? Should I have waited for duo core 2 years ago before I bought my single core...etc. etc., The beat goes on. You would never buy anything if the decision was to wait.

Just curious, but do you live in a smoking environment (pipe, cigar, cigarette, wacky weed, etc.)? At one point there was some speculation that smokers actually shortened the life of their optical equipment, and I think it has been found that smoke residue does cause quite a problem. A couple of tests showed that smoke would settle on the lens, which could cause read errors and with enough buildup, wouldn't read at all.

I experienced this once with a pack a day smoker. His DVD player "died". A lens cleaning disc would let a movie boot, but then it would freeze almost immediately. So I opened up the case, cleaned the optics by hand (you could actually see the smoke residue!), and the "dead" player suddenly worked as good as new.

I recommened that he either stop smoking, or just plan on having his equipment and any exposed discs cleaned every six months. Older players used glass optics, but I think many of the new inexpensive players are using plastic. My guess would be that plastic won't clean the same, and thus, smokers will end up with many more dead players that can't really be repaired economically (you can't just replace the laser assembly, because the spare will likely cost more than a new player).

nope, nobody smokes in our house and because I once worked dealing with laser heads, I usually try to clean them physically once a year and I find that the laserheads in my house are relatively clean of dust.

You are correct, however, plastic lens is more prone to dust and they can't be well cleaned.
