Toshiba’s 240GB MK2431GAH and 120GB MK1231GAL achieve an areal density of 344 gigabits per square inch (531.9Mbit/mm2), the industry’s highest areal density1) in the 1.8-inch form factor, using perpendicular magnetic recording (PMR) technology, which Toshiba introduced and commercialized in 2005. Toshiba’s technology leadership in PMR has enabled the company to consistently deliver leading-edge capacities in the 1.8-inch form factor to support growing demand for miniaturization without sacrificing capacity for digital video, photo, audio and computing applications. The new 1.8-inch HDD series uses a new mechanical and firmware design for enhanced durability, making the 80GB and 120GB single-platter HDDs well suited for slim-line mobile gadgets and PC applications. The new dual-platter 240GB MK2431GAH product is especially suitable for high-end digital video camcorders as well as light-weight mobile PC applications which require high capacity and high shock resistance to protect the users’ valuable digital assets. The new design elements incorporated in the MK2431GAH optimize power efficiency to new levels with a 33 percent overall reduction in energy consumption efficiency2) over Toshiba’s previous-generation model of MK1626GCB (160GB 3,600 RPM) 1.8-inch HDDs…
