Toshiba has unveiled a ground breaking technology that boosts recording density on an 80GB 1.8-inch single platter drive by 50%. Using the Discrete Track Recording (DTR) technology Toshiba was able to pack 120GB storage on a single 1.8-inch platter. The new development will hugely benefit media player, UMPC, and ultra-portable laptop segment where 1.8″ drive with maximum possible capacity are in great demand. Providing 50% increase in areal density of a perpendicular magnetic recording (PMR) the new prototype hard drive takes the recording density to 516 megabits per square millimeter (333gigabits per square inch).
According to the firm, “DTR technology increases recording density by forming a “groove” between the tracks on the PMR medium. The groove reduces signal interference between adjacent data tracks, allowing the pitch of the tracks to be shortened. The improved signal quality also contributes to raising the recording density by 50 percent.” Toshiba plans to start mass production of HDDs integrating DTR technology in 2009.
