Perpendicular recording: A new approach to writing on magnetic media that aligns bits vertically, perpendicular to the disk, rather than parallel to the media, as is the case today. In theory, perpendicular recording should enable higher recording densities as it allows bits to be packed closer together. Last month, disk drive manufacturer Hitachi Global Storage Technologies (HGST) announced it will deliver drives based on perpendicular recording by 2007. With areal densities predicted to be approximately 230Gb/in2, HGST expects to deliver a 1TB 3.5-inch hard drive and a 20GB 1-inch microdrive.
