During playback, the (conjugate) reference beam + recorded hologram act like a filter to reproduce strongly only the info on the particular selected layer... Bragg matching...<br><br>They also didn't explain the readout part too well... you use a data beam and a reference beam to record the disk initially.  When you re-illuminate the disk with a beam "exactly" like the reference beam, the light diffracts from the recorded hologram in such a way as to recreate the original data beam on the other side.  <br><br>Cool, huh?<br><br>What does this mean for you?  Sony's quoting 1.25 GB per layer... with 10 layers, that's approximately 3 standard DVDs with a single laser.  Maybe one of the other tech-heads can give us some other implications of this technology, aka, why it's better than existing methods.]]></description><dc:creator><![CDATA[Loomis]]></dc:creator><pubDate>Oct 19th 2006 12:18AM</pubDate></item><item><title><![CDATA[Comments on Sony demos "cheap" holographic recording technique]]></title><link>http://www.engadget.com/2006/10/18/sony-demos-cheap-holographic-recording-technique/</link><guid isPermaLink="true">http://www.engadget.com/2006/10/18/sony-demos-cheap-holographic-recording-technique/</guid><description><![CDATA[omg!

I assume Evan quoted it directly because he didn't quite get it either. I imagine holographic storage companies like inPhase didn't come up with this method first because, well, it's not a hologram. To spout more jargon, it's essentially confocal interferometry, but it records only 1 bit per fringe pattern. A hologram's advantage over standard serial data recording techniques is based on the fact that with a spatial light modulator you record a 2 dimensional array of data (like a grid of bits) in parallel, as opposed to one bit at a time. This technology, as seems pretty clear from the graphic on the linked Japanese site, records individual bits in a serial fashion like standard optical disc technology, it just stores the data differently, i.e., as interference fringes as opposed to pits. Moreover, the technique apparently encodes the information with a mechanically actuated mirror, as opposed to electrical modulation of a laser's intensity in a conventional optical storage device. This technique should allow writing to multiple layers in medium, but it is not holography, can not be as fast as holography, and doesn't threaten (or matter much) to companies like inPhase and Optware.]]></description><dc:creator><![CDATA[Once Optical]]></dc:creator><pubDate>Oct 20th 2006 9:35AM</pubDate></item></channel></rss>
