p2pnet.net news special:- One of the really cool things about being online is the people you meet, people you’d be unlikely to come across in any other way. And that accurately describes Michael Thomas, a US data storage innovator p2pnet first featured in 2004 as the inventor of the Atomic Holographic DVR disc drive.

He’s still out there inventing incredible technology which is usually so far advanced as to resemble pure sci-fi but which, IMHO, will one day be standard.

Here he is with optical spintronics, data storage for the future >>>>>

Spin electronics or Spintronics has become a hotbed for research not only in semiconductor technology but new optical data storage concepts. It’s a difficult subject to understand and talk about because of the complex issues involved.

Spintronics is the ability to change or influence the rotation of an electron.

How’s is this done?

Well first, it’s important to understand a few fundamentals about electrons.

Electrons have the basic properties of spin, charge, and mass. That the electron has superposition (being everywhere) at the same time, where theory states you can only know certain values but not simultaneously, one pair is momentum and position, and the other is energy and time. Electrons have 2 spin states +spin up and -spin down which are usually found in paired electrons. No 2 electrons can occupy the same quantum state. +spin up has less quantum energy than - spin down. Electrons absorb photons quantum energy to change valence orbits, and they lose spin coherence by colliding with mutually resonant photons frequencies causing the electron to spin flip by energy transfer through mutual spin-orbit coupling and photon emission.

They can be measured by decoherence, which is taking a snap-shot of an electron, realizing what was observed really didn’t exist anymore. Electron spin is defined by intrinsic angular momentum which some believe is the reason for the electron’s internal electron magnetic radiation field. Electron rotation around an atom is orbital momentum. Spin rotation of an electron can be influenced by resonant polarized photons of the correct quantum energy. Alternating AC electric field (electromagnetic) and static DC field (electrostatic) can deflect an electron which has a negative single electrical charge.

Spintronics isn’t new to storage. All present day hard drives use giant magnetoresistance effect, or GMR. The effect manifests itself as a significant decrease in resistance from the zero-field state, when the magnetization of adjacent ferromagnetic layers are antiparallel due to a weak anti-ferromagnetic coupling between layers, to a lower level of resistance when the magnetization of the adjacent layers align due to an applied external field from the recorded data on the magnetic disk.

The spin of the electrons of the nonmagnetic metal align parallel or antiparallel with an applied magnetic field in equal numbers, and therefore suffer less magnetic scattering when the magnetizations of the ferromagnetic layers are parallel.

Electron spin is detected by the read part of the disk GMR drive head using electron spin from one material that changes orientation due to electromagnetic radiation, and another that doesn’t but is influenced by the electrons of the material that does change. Laser or photons can’t be used for ferromagnetic material used in disk drives because photons destroy the orientation of the 0s and 1s, or severly damage the orientation.

Today’s hard drives can’t use electromagnetic flux transversal to write or cause individual electron spin. In general, they cause many magnetic particles in an area on the disk to change magnetic direction from north to south. The number of magnetic particles needed for the GMR head to be able to tell 0s and 1s apart is defined by terms like margin, bit density, resolution, overwrite, signal to noise ratio, write and erase currents, bandwidth of the data channel, track density and many other measurement terms related the inductive BH coercivity of the magnetic recording material.

Data storage demands have contined to increase from 5 Exabytes in 2003 to last year’s 160 Exabytes of new data. The first part 2010 is expected to see 600 Exabytes of new data, with end of 2010 about 1 Zettabytes of new data and growing!

Present day hard disk drive data storage technology is lagging behind, an unfortunate reality which will start to impact internet performance. This is even predicted by what’s called the Super Paramagnetic Limit for magnetic storage because the signal to noise ration can’t be overcome. The energy needed for writing 2 flux transversals is too great, having heat and vibration problems.

Optical Spintronics for optical data storage is the future because it can use much higher electro magnetic spectrum frequencies with functions taking advantage of controlling the electrons for use in reading and writing of stored information while maintaining non-volatility and extending the shelf life beyond magnetic hard drives capabilities.

Colossal Storage proposes using ferroelectrics because the bit densities can be scaled down to the nanometer while still maintaining non-volatility of the bits using interference, diffraction, reflection, entanglement, electrostatic fields, electromagnetic fields, and spintronics for data detection. In ferroelectric materials, the molecule has physical properties called multiferroic that have an electrostatic field and an EMF field that are 180 degrees out of phase, and rotated 90 degrees from the x-axis.

Molecular dissociation for a non-contact photon induced electric field poling using UV space charge fields at the same wavelength as a molecular transition will create controllable clouds of electrons in harmonic waves (Plasmon). Some organic/inorganic molecules have resonant valence orbit electrons that under the proper UV space charge field photo excitation will allow polarized conduction band electrons to move freely for a short time (popular inversion).

Plasmon (electron movement between valence and conduction band), known as spin polarized electric current along with the electric field present, provide a mechanism for ferroelectric perovskite molecules central atom to switch dipole geometric positions.

The unique concept of resonant absorption excitation (electrons have specific quantum energy requirements for valence to conduction band movement ) by UV/Blue laser light illumination causing molecular/electron dissociation and simultaneous electric field application (Pockels effect) can be used for writing 2D Area or 3D volume data.

When the data are read back, the molecule will have coherent interference waves in a beam of soliton wave (waves in EMF phase) photon radiation (below popular inversion - number of electrons not in valence). By using different quantum energy circularized polarized UV photons electron spin of the electron can be controlled. Movement of the electrons in the molecule can be controlled by disk rotation (generator effect), electric field, and resonant photons to use the electrons movement in a molecule generating internal current (electron movement) to the ferroelectric molecule which allows for central atom in the ferroelectric molecular dipole to switch.

Ferroelectrics have the unique ability to maintain an electric charge, much like battery which can be negative or positive with approximate values from .6 to 6v. Their optical properties, and the fact they have both magnetic and electric fields simultaneously, adds to the possibility of extremely dense 2 dimensional and 3 dimensional nanotechnology material whose internal physical geometry properties can be configured over and over again.

For ferroelectric spintronics to work, there needs to be dynamic current flow to cause movement of the electron using intrinsic properties of the electron and molecule effected by electro magnetic fields, electric fields, and photon excitation. The Faraday Effect can, therefore, be created by vertical movement of the electrons in a rotational field further influenced under an electric field and UV electromagnetic polarized light. Where the magnetic fields of the individual electrons fields are parallel at some point along the polarized UV boundary, the possibility for directional spin current change of the electrons from spin up to spin down or vice versa is opened up. When groups of electrons spin in the same direction, ie spin up or spin down, the electro static and magnetic fields associated with all the electrons can add up to one large electric and magnetic moment 100 to 1,000 times greater than normal. Methods and functions for controlling electron spin up and spin down can be used to drastically increase data storage densities.

Non-Invasive Spintronic techniques using a non-contact mosfet transistor to retrieve the electron states of the multiferroic ferroelectric molecule will allow for the creation of very dense storage having non-volatility without causing decoherence of the data.

Ferroelectric densities of .2 to .5 Petabits = 200 to 500 Terabits sq. in. / 40 Petabits = 40,000 to 100 Petabits = 100,000 Terabits cu.cm. or 200,000 to 500,000 Gigabits sq.in. / 40,000,000 to 100,000,000 Gigabits cu.cm. with symmetrical read / write times of < 10 picoseconds for 100 year non-volatile storage having infinite rewrites.

Without new innovative data storage nanotechnology addressing the need for continued data storage demands we cannot expect the technology industrial revolution to continue.

Stay tuned for a p2pnet special on a mobile direct energy system which, if it’d been around at the time, might have at least partially averted the 911 disaster.

Involved are Thomas, ex-US Navy Seal communications specialist Captain Bob Adams, now runnng the Optima Technology Group, and Jed Margolin of Atari fame.

Hint: Adams told p2pnet his favourite game when he was growing up was Missile Command.
