Sharp developing new Blu-ray laser

Next up, sharks with Blu-ray lasers on their friggin' heads!

Next up, sharks with Blu-ray lasers on their friggin' heads!

Last weekend, Sharp revealed a powerful blue-violet laser that the company hopes will lead to triple and quad layered Blu-ray discs.

For tech heads, Sharp has achieved this technology by constructing a 500mW laser with an aluminum oxynitride layer between the laser’s crystal and the dielectric film that protects the laser. Previous lasers have lacked the crystalline dielectric film necessary to pull off the feat.


What does this mean for the layman?


Sharp’s breakthrough in Blu-ray technology could not only lead to quad-layered discs (with up to 100GB in total storage capacity), but 8x write speed as well.


After Sharp unveiled the laser at the Autumn Meeting of the Japan Society of Applied Physics, the company confirmed that it had rigorously tested the new laser and verified its reliability after thousands of hours under intense heat.


The company also announced it was capable of mass producing the technology, but was waiting for the Blu-ray Disc Association (BDA) to determine the specifications for triple or quad-layered Blu-ray discs.


The possibility of burning an entire digital music library on one disc has us salivating, though.

    Thanks for this unique insightful information. Often, the best answers originate from the sites you may not expect. So far, I failed to give so much thought to placing comments on blog page entries and have left feedback even less. Reading through your positive content, will help me to take action more regularly.

    Right now Sharp can’t get the Blu Ray Software release that will allow Avatar/ Blu Ray version to play on their BDHD16, BDHD17U or BDHD22U machines correctly. Here it is April 26th,2010 & they have know since January this movie would be released to DVD /Blu Ray this year

    Yet the 2 Year old Sony Blu Ray with a software update from last year will play Avatar correctly & no problems on Day 1 of the release.

    Sharp needs to keep their customers happy or there will be NO REPEAT buyers of Sharp products..

    I know I’m a little late in contributing my thoughts but this particular article made me think. It was an engrossing piece. I have become a frequent visitor to your blog since I found your blog a while back. I can’t say that I agree with all you mentioned but it was definitely intriguing ! I operate a small establishment that secures funding for businesses in the Houston market. You could say I focus in Houston Commercial Financing and deal with folks that banks won’t deal with anymore. I’m helping to create American jobs so I hope you’ll allow me including my link in this post. I’m always seeking to promote our truly unique service and am the type of person who still believes America keeps getting better and better in spite of our current difficulties. I’m not sure if my other post was successful so I’m attempting again. Thank you again for an enlightening blog post. I will return again soon.

    Crazy.

    One other thing is that an online business administration training is designed for scholars to be able to efficiently proceed to bachelors degree education. The 90 credit education meets the other bachelor education requirements and once you earn your current associate of arts in BA online, you will possess access to the most recent technologies on this field. Several reasons why students want to get their associate degree in business is because they can be interested in this area and want to receive the general instruction necessary in advance of jumping right bachelor diploma program. Many thanks for the tips you really provide within your blog.
