Il mondo in tasca. (Da Berkeley: sempre piu' bit in sempre meno spazio)

10 terabit per pollice quadrato.

Sulla superficie di una moneta da un centesimo ci stanno 400GB, (un tanto al chilo, 3-400 film).

Secondo il ricercatore puo' scalare (economicamente sostenibile) di un ordine di grandezza, cioe' 100Tb per pollice quadrato. per adesso ha dimostrato i 10 Tb.

02.19.2009 - New method to assemble nanoscale elements could transform data storage industry.

BERKELEY — An innovative and easily implemented technique in which nanoscale elements precisely assemble themselves over large surfaces could soon open doors to dramatic improvements in the data storage capacity of electronic media, according to scientists at the University of California, Berkeley, and the University of Massachusetts Amherst (UMass Amherst). Schematic of self-assembly of nanoscale elementsThe sawtooth ridges formed by cutting and heating a sapphire crystal, shown at top, serves to guide the self-assembly of nanoscale elements into an ordered pattern over arbitrarily large surfaces. Researchers say the new, easy-to-implement technique may transform the data storage industry. (Dong Hyun Lee/UMass Amherst) "I expect that the new method we developed will transform the microelectronic and storage industries, and open up vistas for entirely new applications," said co-lead investigator Thomas Russell

With this technique, the researchers were able to achieve defect-free arrays of nanoscopic elements with feature sizes as small as 3 nanometers, translating into densities of 10 terabits per square inch.
