Toshiba Prototypes 120 GB 1.8" Single Platter Drive
Currently, Apple uses an 80 GB single-platter drive for its thinner model and a 160 GB dual-platter drive for its slightly thicker model. Toshiba's technology would allow single-platter models to achieve 120 GB densities, with a dual-platter option going as high as 240 GB.
Toshiba plans to begin mass producing the drives in 2009.
