Longitudinal recording Last modified: Monday, May 01, 2006
A method of recording data to a hard disk drive (HDD). Used over the last 50 years, Longitudinal recording aligns data bits horizontally in relation to the drive's spinning platter, parallel to the surface of the disk. Contrast with Perpendicular 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.
