  1. 1956 IBM Model 350 Hard Drive

  2. 5MB! 2000 lbs $3,000/month

  3. Just like Moore’s Law exponentially GBs 1980 1990 2000 2010 Time

  4. Just like Moore’s Law $1,000,000 exponentially $/GB $1,000 $1 1980 1990 2000 2010 Time

  5. Trillions of tiny magnets 100 nm 50 nm

  6. tiny electromagnet 7200 rpm

  7. Electromagnet Flying at 10 m/s Hard Disk 2 nm

  8. 600 mph 50 nm Ground

  9. Next technology = Heat-Assisted Magnetic Recording

  10. Scientific American Not so scientific 10,000 nm laser beam diffraction limit 200 nm 1 Bit 20 nm

  11. 10,000 nm laser beam My research: focus light to 20 nm for $1 diffraction limit 200 nm 1 Bit 20 nm

  12. Antennas (really tiny ones) λ = 800 nm Light

  13. Most efficient antenna?

  14. commercial in 2– 3 years
