Lens That Writes on Both HD-DVD and Blu-Ray

morpheus83 writes "Ricoh claims they have developed an optical component that reads and writes all disk formats -- Blu-ray Disc and HD-DVD, as well as DVD and CD -- with one pickup and one objective lens. The 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. Based on disc information the drive can identify which format disk is loaded, Ricoh's optical diffraction component adjusts the laser beam with its diffraction grating for each format and passes it to the objective lens."

    For someone who's supposedly been a "professional software developer and systems integrator for the past 25+ years" your spelling (and grammar) is atrocious! I counted 23 errors in your post. In order: "anythying" should be "anything" "etc etc." should be "etc., etc." "XBOX" should be "Xbox" "matter.(This" should be "matter. (This" "stats)" should be "stats.)" "BLURay" should be "Blu-Ray" "IN" should be "In" "capacitied" should be "capacities" "But, backup" should be "But backup" "buy" should be "by" "anywhere" should be "anything like" "so, Well " should be "so? Well " "don't:-" should be "don't:" "DVD" should be "DVDs" "PC's" should be "PCs" "MP3's" should be "MP3s" "PC's" should be "PCs" "Ipod" should be "iPod" "shoot'em up" should be "shoot'em-up" "BluRay" should be "Blu-Ray" "tat" should be "that" "100Gb" should be "100GB" "hat" should be "hat." And I'm not even counting the lack of a period at the end of your sig. If you're going to boast about your geek status then please write like you deserve it.
