Hi am Priyanka i would like to get details on nanotechnology based data storage ..My teacher said nanotechnology based data storage will be available here and now i am living at ..shirur....... and i last studied in the college .....c.t.bora college.... and now am doing ...bcs.i need help on ......etc

Data storage is one of the key elements in information
technology. The ever increasing demand for more storage
capacity in an ever shrinking form factor as well as the
pressure to decrease the price per storage unit in $/Gbyte
have been a major driving force for substantial worldwide
research and development activities to increase
storage densities by various means.
For many decades, silicon-based semiconductor
memory chips and magnetic hard drives (HDD) have been
dominating the data-storage market. So far, both technologies
have improved their storage densities by about 60100% per year, while reducing the cost per gigabyte.
However, the areal densities that todayís magnetic
recording technologies can achieve will eventually reach a
limit imposed by the well-known superparamagnetic
effect, which today is conjectured to be on the order of
250 Gbit/in.2
for longitudinal recording. Several proposals
have been formulated to overcome this limit, for
example, the adoption of patterned magnetic media,
where the biggest challenge remains the patterning of the
magnetic disk in a cost-effective manner. In the case of
semiconductor memories, such as DRAM, SRAM, Flash
etc., the challenges are predominately in lithography to
define and fabricate sub-100-nm FET gates as well as
very thin gate-oxide materials.
