It certainly sounds great. A far denser read/write
storage system is essential, if science is to progress.The theory seems fine, to put it into practise, would be difficult.
the blue laser diode is a recent (Japanese)development. Understanding the laser writing to a doped film of Lithium Niobate is fine. But first one has to control dope your Lith Nio: using a similar technique in forming synthetic ruby (from a boule, using HF heating) Then one has to bond the Lith N film to a (disk?)substrate.
For maximum packing, the data should be placed at diff depths. Continual refocussing the blue laser is a technical no no, (power and time waster) So I expect a revolving mirror might be a 3D depth method....which unfortunately would make it near immpossible to be correctly re-read upon another similar system?
Its my experience that while the inventor opts for, and continues his quest for his super better system.
Other companys will bring out a less efficient system, and actually make money for a few years.
I expect two layer DVD writers will come out before the end of this year. Allowing copying of DVD's on the fly, negating the need to waste time uncommpressing and re-compressing from a Hard D.Prehaps simpler high storage methods will be adequate, and used for the next few years, until
doped Lithium Niobate really hits the headlines.Vertical paramagnetic domains on a disk are Ok, but limited to domain size and packing. High disk speeds, might not be read accurately?
Silver doping of a glass disk (similar to PhotoChromic sunglasses) Very fast reacting to
a strong photon source. No info on this.
Quartz disc? or better, quartz fiber blasted with a microwave radio source (changes the quartz internally)storage only?
Whatever method is used for the next few years the winners are the Military and the public.I have the utmost admiration for Michael E.Thomas
the Inventor, and his Company - Colossal Storage
for using Scienceagogo to post his wonderful ideas
and patents. I wish him well.
