- Sony announced a blue laser device, with a wavelength of about
- 440 nm. this might enable a three-fold increase in storage
- density.

- what some sources (e.g., The NY Times ) failed to mention is that
- the devices work at something like -300 F. it's possible that the
- devices can be made to work at "room" temperature, but don't hold
- your breath. seen any room temperature superconductors lately?
