With Apple launching their new iPod classic, pretty much everybody is now aware that 1.8-inch hard disks max out at 160GB. Thing is, that disk -- be it from Toshiba or Samsung -- is actualy spinning a pair of 80GB platters at its core. So what would you say to Toshiba's announced 120GB single-platter drive? Hoozah, seems appropriate. The new prototype applies Discrete Track Recording (DTR) technology to boost the areal density of perpendicular magnetic recording (PMR) techniques by a full 50% -- that's 516Mb per square millimeter (333Gb per square inch). Tosh plans on mass producing the 1.8-inch and 2.5-inch (laptop) drives in 2009 which means that a 240GB "iPod HD" can't be too far away, eh Apple?
