Toshiba already rules the 1.8 inch HDD segment with a market share of 85%. Now they have come up with a new HDD with Perpendicular Magnetic Recording (PMR).
As of now this HDD is for CE devices like Portable Media Players, Gaming console, Imaging devices etc., This technology is based on a new magnetic disk structured to support perpendicular recording, a new high-performance perpendicular magnetic head, and disk and head integration technology that maximizes their combined performance. Conventional method is the Longitudinal Recording, which stores data on a magnetic disk as microscopic magnet bits aligned in plane.
I still have a 40MB HDD, which was manufactured by Seagate in 1990's, which is in the size of today's desktop HDD. But see the difference in the capacity!!!!
