Holographic Disk Drive Technology

  1. 1. Holographic Disk Drives: <ul><li>The New Frontier of Data Storage </li></ul>
  2. 2. Today’s Presentation Brought To You By: Richard Rumley
  3. 3. Introduction <ul><li>Holograms and Lasers </li></ul><ul><li>Blu-Ray: The Predecessor </li></ul><ul><li>What exactly is a holographic disk? </li></ul><ul><li>Blue lasers and how it all works. </li></ul><ul><li>Potential problems identified. </li></ul><ul><li>Holographic Technology: Paving the Way For The Future of Data Storage </li></ul>
  4. 4. Holograms & Lasers <ul><li>A hologram is a photographic image that appears to have depth or more commonly referred to as 3-D. </li></ul><ul><li>Produced by 2 laser light beams reflected from two slightly different reference points similar to how we are able to see in 3-D. </li></ul><ul><li>Developed and printed on two ultra-thin curved silver plates. </li></ul><ul><li>Reflection of light from these 2 plates similar to how a prism works and thus produces a 3-D image. </li></ul>
  5. 5. Blu-Ray: The Predecessor of 3-D Data Storage <ul><li>Holographic data storage is made possible by the same blue laser light that is used in Blu-Ray technology. </li></ul><ul><li>The footprint of blue laser light is much smaller than that of red laser light. </li></ul>
  6. 6. What Is A Holographic Disk? <ul><li>Developed by InPhase Technologies a spin off technology from Bell Laboratories in 2000. </li></ul><ul><li>Blend of 2 polymers. </li></ul><ul><li>One is highly photosensitive. </li></ul><ul><li>Holographic image within the substrate. </li></ul><ul><li>The protective cartridge. </li></ul>
  7. 7. Blue Lasers & How It All Works <ul><li>One blue laser light source 2 beams. </li></ul><ul><ul><li>The reference beam which reads the data. </li></ul></ul><ul><ul><li>The second “writes” a </li></ul></ul><ul><ul><li>3-D image of the data. </li></ul></ul><ul><li>The spatial light modulator which translates the data into a “checkerboard” of pixels that make up the image. </li></ul><ul><li>The media upon which the holographic image is recorded. </li></ul><ul><li>Reading & Writing the data. </li></ul>
  8. 8. Potential Problems Identified <ul><li>The holographic disk’s 50 year lifespan. The 8-Track tape a good example of media outliving the technology. </li></ul><ul><li>The price tag for the drive and disks. </li></ul><ul><li>Targeted market group confusion. </li></ul><ul><li>Next technological breakthrough. </li></ul>
  9. 9. Holographic Technology: Paving the Way For The Future of Data Storage <ul><li>Holographic data storage is still in its infancy, with still plenty of room for improvement. </li></ul><ul><li>With improvement there is little doubt this technology will have a huge impact on the IT world. </li></ul><ul><li>Just a thought ~ </li></ul><ul><li>Smaller is definitely better! </li></ul><ul><li>Using UV laser light is the future of data storage. </li></ul><ul><li>Still far into our future. </li></ul><ul><li>Requires manipulation of sub-atomic particles. </li></ul><ul><li>Not possible with today’s technology. </li></ul><ul><li>Each new breakthrough brings us another step closer. </li></ul>
  10. 10. This Concludes Today’s Show! <ul><li>Thank You For Your Attention! </li></ul>
