Toshiba DTR vs PMR

Toshiba announced some breakthroughs in magnetic storage that could theoretically see the 1.8″ hard drives pushing 240GB using two platters. Using a new process which adds grooves to the disc surface, Toshiba have been able to get 120GB per platter. Apparently this process is best suited to small drives such as 1.8″ & 2.5″ drives. Although this would mean a nice fat drive in our iPod, this process is expected to reach the manufacturing process in 2009.
