A chip to punch card  

Details of A chip to punch card



The scientists of prestigious IBM of Zurigo have conceived a system that allows to store until a terabit of information on a great support like a stamp. The used principle is identical to that one of the punch cards once.

In fact, the data come memorizza you on the card under shape of smallest holes, conceived from one head situated all`estremità of a mobile device, that it writes, law and cancel the information.

Currently 1024 arms, able have been created having cards prototype to conceive holes of the diameter of 40 nanometers. L`intera structure memorizzato until 200 gigabit of data in a space of single six centimeters square. The scientists but have carried a.termine with succeeding of the tests creating, with a single arm, of the holes still more small. In this way the memorization ability has been increased carrying it to a terabit.

According to Peter Vettinger, director of the plan, this is the appropriate technology for the devices portable you. On the card c`è one surface composed from one layer of plexiglass on a silicon substrate. The chip it comes carried to 400 degrees, suitable temperature in order to create the holes on the plexiglass. While in order to cancel the data the tip heats only the margins of the holes, richiudendo them.

He will want still various time to us so that this technology can be used in practical applications, but the scientists dell`IBM of Zurigo, with great seriousness and professionality, want nearly to defy the time: they are themselves fixed l`obiettivo to put to point a already working prototype all`inizio of the next year.
