These examples show synthetic, non-data-driven animations, created to visualize complex technological processes.


Magnetic Resonance Force Microscope

MRFM Graphic Micromechanical sensing of magnetic force was used to detect nuclear magnetic resonance with exceptional sensitivity and spatial resolution. The results suggest that magnetic force sensing is a viable approach for enhancing the sensitivity and spatial resolution of nuclear magnetic resonance microimaging. The envisioned "magnetic resonance force microscope" would have elemental identification capability and be able to determine nuclear positions with subangstrom spatial resolution in three dimensions. Such an instrument, if it could be built, would represent a revolutionary advance for the field of magnetic resonance imaging and would greatly facilitate the determination of molecular structures.

Thermomechanical Writing with an Atomic Force Microscope Tip

AFM Graphic A focused laser beam propagates through the transparent PMMA sample and heats the optically absorbing AFM tip. The heated tip softens the substrate, and the local tip pressure creates an indentation. The sample is placed on a precision air-bearing spindle to allow for sample rotation. Here is a schematic figure of ths process.

A paper about this technique has been published in Applied Physics Letters (H.J. Mamin and D. Rugar, Appl. Phys. Lett. 61 (8), 1003 (1992)).


Multilevel Optical Disk

MOD Graphic Scientists at IBM's Almaden Research Center have demonstrated new multilevel optical disks that are capable of huge gains in optical disk data storage capacities.

Here is some more information and here is a short animation MOD Movie (73 kB) showing the principles.


Magnetic Data Storage

MDS Graphic As the areal density of magnetic recording increases, the radial spacing of the circular tracks onto which are written the magnetic bits decreases. This requires improved control of the servo system which maintains the recording sensor over the center of the track. A possible solution is the use of a microactuator, located near the recording sensor, which has sufficiently rapid response and sufficient force to move the magnetic recording head carrier.

Blue Laser

Blue Laser Graphic By means of smaller wavelength and new data coding techniques, the invention of the blue laser allows the storage of up to five times more data on a optical disk than with a conventional infrared laser.
