Transcript

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