Perpendicular recording Last modified: Monday, May 01, 2006
A method of recording data to a hard disk drive (HDD). Perpendicular recording aligns data bits vertically — perpendicular to the disk, which allows for additional room on a disk to pack more data, thus, enabling higher recording densities. Contrast with Longitudinal recording. Also see "What Is Perpendicular Hard Drive Technology?" in Webopedia's "Did You know..." section.

TechWorld: Perpendicular Recording The amount of data that we can store on a disk surface, in this way, is approaching its limit. As we seek to reduce the size of the charged particles we increase the risk of distortion. As a result increased areal density, the holy grail of disk manufacturing in recent years, is becoming ever hard to meet.
