Sharp plans 8x+ Blu-ray burners by 2010

by Richard Lawler, posted Mar 25th 2008 at 7:39PM

Sharp is continuing to move the bar in blue laser technology, recently unveiling a higher power (250mW) 6x Blu-ray recording laser, but more importantly tipped its hand regarding plans for 8x blue laser diodes by 2009. Those lasers will be able to output 300mW, followed by 400mW varieties capable of up to 12x speeds by 2010. Looks like blue laser shortages are a thing of the past, now we'll see how quickly speed -- and possibly multilayer discs -- can ramp up.

Atmel intros 'industry's smallest' laser diode driver for HD DVD / Blu-ray

by Darren Murph, posted Jul 24th 2007 at 11:01AM

Atmel, the same firm known for cranking out uber-small GPS chips, has now created the "industry's smallest laser diode driver solution" for HD DVD, Blu-ray, DVD, and CD formats. The ATR0881 laser diode driver IC is available now and is designed for use in combination drives that play nice with all of the aforementioned discs. Notably, the ATR0881 itself is housed in a minuscule four- x four-millimeter QFN24 package, and should prove extremely useful in half-height combo drives as well as slim drives found in laptops. Smaller optical drives that handle every format harmoniously? Count us in.

Blue lasers coming down in price, PS3 to follow?

by Erik Hanson, posted May 1st 2007 at 11:11AM

Blue laser assemblySony's semiconductor subsidiary recently announced an increase in blue-violet laser diode production, with a monthly capacity of 1.7 million, and capability to produce up to five million with future upgrades. In June the diodes are expected to cost around $8 per diode in bulk, as compared to a price of $125 per drive (including the diode and other parts) when they came onto the market last year. Analysts predict that the lower cost of materials will likely drive manufacturers of blue-laser products to lower their own prices, with the PlayStation 3 benefiting from this reduction by allowing Sony to reduce the price, possibly even lower than $499, to be very competitive with the Xbox 360 Elite model. Of course, Toshiba could also theoretically take advantage of similar cost savings to reduce the price of their own HD DVD players. Perhaps that Wal-mart player isn't such a far-fetched idea after all.

Cheaper blue lasers on the way?

by Richard Lawler, posted Feb 26th 2007 at 12:13PM

Whether the format war is over or not, one thing that would definitely get more buyers off the fence and owning more high definition players would be lower prices. Aonex Technologies and Kyma Technologies are the latest to announce they've found a better (and cheaper) way to pump out the blue laser diodes necessary in every Blu-ray and HD DVD player. Aonex claims its A-Sapph wafer technology improves on current sapphire based processes, enabling an increase in the number of chips per wafer and improving yields substantially. As fans of lasers in general, and not just in relation to HDTVs and lower prices, we're excited, but without even the hint of an expected release date it will probably be a while before these are ready for the market.

Sanyo's blue laser to speed up HD DVD / Blu-ray burning?

by Darren Murph, posted Jan 11th 2007 at 2:02PM

While Sony's certainly had its fair share of blue laser supply issues, and the current generation of HD DVD / Blu-ray burners are sluggish at best, it looks like the first step towards marginally acceptable write speeds to next generation formats has been taken. According to Nikkei, Sanyo has developed a blue laser diode which will speed up data access, and moreover, should be able to reach write speeds of "up to 6x for dual-layer discs." Similar to LG's combo unit, this diode also plays nice with both HD DVD and Blu-ray recorders, but there's no word if a hybrid writer using the laser is in our immediate future. Still, any progress towards harmony between the formats -- not to mention being able to burn a dual-layer Blu-ray disc in time for your next birthday -- is a step in the right direction, so we're expecting nothing less than a 6x burner to be hitting shelves sooner rather than later, Sanyo.

Blu-ray vs. HD DVD on hold for blue laser shortage?

by Richard Lawler, posted Aug 29th 2006 at 10:44AM

As much as we like to talk about the ongoing format war between Blu-ray and HD DVD and our readers comment on it, the simple fact is that very few of us actually own either format yet. This is definitely related to the high prices and growing pains early adopters are subject to but the fact is neither one is available in significant quantities yet. As more manufacturers prepare to jump in to the battle this holiday season they may not be able to because of their shared reliance on blue lasers. Only a few companies worldwide produce them and none have been able to get very good yields. Even Sony, who produces blue lasers for themselves and others, has predicted a shortage as they seek to roll out the Playstation 3 and BDP-S1 and according to this article, have suspended shipments to others. For manufacturers who have to rely on someone else for a supply, this could mean a delay until 2007 before many players and drives are launched.
