    Ricoh has reportedly invented a technology which allows a single laser to read and write all currently available types of optical discs, e.g. Blu-ray discs, CDs, DVDs and HD DVDs. Potentially, this may end the format war in the consumer electronics space, as all manufacturers will be able to support both competing standards – Blu-ray and HD DVD – without much additional spending.

    The data layer of the Blu-ray Disc resides 0.1 mm from the disk's surface, while the HD-DVD data layer is 0.6-mm deep from the disk's surface, the same as DVD disks. CDs have a data layer depth of 1.1 mm from the disk surface

    Ricoh's component is a 3.5-mm diameter, 1-mm thick round diffraction plate with minute concentric groves on both sides which function as a diffraction grating.

    The diffraction plate is placed between lasers and an objective lens. The diffraction grating is designed to adjust a light beam to an optimum incident ray relative to the objective lens so that light focuses on the proper position for each disk format, and therby allows you to read and write to the disk.

    I was expecting something like this to come out eventually, I'm just wondering if it has to use more than one laser to read all formats or whether it is an all-in-one super laser.

    I doubt it...the super laser is trademark of Seinar systems and Imperial cruisers are the only one's that can use those things :p (think about star wars if you're confused lol.).

    It was only a matter of time and here is hoping this stops the stupid format wars which us punters would end up paying for.

    Format wars are retarded. Should just go with the most technnically advanced option. Or support both formats :D

    Haha, I feel sorry for anybody getting a PS3 if they scratch their disks. CD can be pretty banged up and play fine, DVD can take a few scratches, but look, blueray is 6 time closer to the surface of the disk.... just use your imagination, there are going to be a lot of $50 frisbees :laugh:

    More like $80, considering console game prices going up, the difficulty of coding the PS3's processor, and "collectors edition" lol. And we still don't want to be using super-lasers on a regular basis...the empire already destroyed Alderann and a few rebel cruisers, lets not add the moon to that list :p.

    Zek... I find your lack of faith disturbing. Super lasers are insignificant compared to the power of the force :laugh:

    Off topic: while we're talking of star wars KOTOR II is an amazing game. Can't wait for the next one and I may buy the first.
