longitudinal magnetic recording
A computing term referring to a method of magnetic recording where the magnetization is aligned horizontally along the recording medium, as opposed to perpendicular recording.
Longitudinal magnetic recording is one of the recording methods for hard disks.
Perpendicular magnetic recording, where magnetization is aligned vertically, allowing higher data density compared to longitudinal recording.
Compound of 水平 (horizontal) + 磁気 (magnetic) + 記録 (recording).
