This is funny. I just blogged about the new perpendicular storage technology (which is estimated to give 230 gigabits per square inch - which is about 29 GB per sq.in.). Well, how about about a harddisk that stores four times more than that?

Physicists in the US and Germany have reported on a new way to double the storage capacity of magnetic recording devices. The method, which is compatible with standard lithography fabrication techniques, could help overcome the limits of conventional magnetic recording and allow storage densities of 1 terabit (1012) bits per square inch (M Albrecht et al. 2005 J. Appl. Phys. 97 103910). The increase in storage capacity is made possible by combining arrays of magnetic dots with multiple magnetic layers.

P.S. Looks like I must add a "Storage" category on my blog. Too much interesting stuff is going on... :-)
