Maximum data that a disk can accommodate discovered Washington:
Researchers have claimed to have discovered the peak amount of data
that can be crammed into a hard disk. Professor Harald Brune from the
Ecole Polytechnique Federale de Lausanne (EPFL) along with his colleagues
created a self assembled lattice of non-interacting two-atoms-high islands
of cobalt on a single-crystal gold substrate and recorded a density
of 26 trillion islands per square inch. This, studies showed was 200
times the bit density of current computer hard disks. He said that since
the islands never interacted with each other, they were capable to individually
hold one bit of data. He however, said that it was not a storage medium
"ready to use" as these records were posted at the uncomfortably cold
temperature of -223 C. Above this temperature, he said, thermal excitation
starts to reverse the magnetization and the information in the memory
gets volatile. As of now, Prof. Brune and his colleagues are trying
to solve this blocking temperature problem using bi-metallic islands
of 500-800 atoms that can maintain the desired magnetic properties at
room temperature. References: India Travel Times, News, Hotels, Airlines, Indian, Tourism, Tourist, Tour, Ayurveda, Yoga, Hotel |
