Kunal Hemrajani 1 Report post Posted January 1, 2007 Researchers have demonstrated a simple new way to focus laser beams to a much tighter spot than is possible with conventional lenses and mirrors, making it possible to store up to 3T (terabytes) of data on a CD-sized optical disk. Applied Physics Letters 89: 093120 details the research results of integrating a resonant optical antenna right on a laser (which would make it relatively easy and economical to do commercially.) Spot sizes of 20 nanometers have already been achieved. Just by way of comparison, the new high-definition DVDs including Blue-Ray only store about 25G per side with their much larger dot size. Reading between the lines (so to speak) since I didn’t pay to see the whole article, the new approach appears to use two tiny antennas and thus probably works on an interference pattern basis but that doesn’t really matter unless you are designing lasers, the point is that it appears to work and be commercially viable even for relatively inexpensive devices like today's CD-R and DVD-R drives. Achieving cheap terabyte storage capacity would probably trigger as big a technology revolution as the original CD-ROM did. But my point is we r stil waitin 4 Blu-Ray to become economical..

HetalDP 947 Report post Posted January 1, 2007 Logic is Simple for Cheaper Rates Large Volume Production and Older Tech When DVD Come CD Prices get Dropper When Blue Ray was There DVD Prices are Dropping Same wil be Case When Tera Byte DVD will Become a Reality We could Have BR-DVD or HD-DVD in Range of Rs. 100 or much cheaper Share this post Link to post Share on other sites

Honest 836 Report post Posted January 1, 2007 (edited) ^^^ Oh my dear StaticElectricity, storage of over 1.6TB, thats a great news. Regards. Edited January 1, 2007 by Honest Share this post Link to post Share on other sites
Kunal Hemrajani 1 Report post Posted January 2, 2007 yaar.. i was jus wondering hw cud i fill that 1.6TB of space??.. but anyways technology wil keep on progressing.. and we wil never b satisfied wid it.. Share this post Link to post Share on other sites
