noun
perpendicular magnetic recording; vertical magnetic recording
Technical term in computing and data storage; refers to a method of recording data on a magnetic medium where the magnetization is aligned vertically (perpendicular to the disk surface) to achieve higher density.
垂直磁気記録はハードディスクの高密度化に貢献した。
Perpendicular magnetic recording contributed to higher density in hard disks.
Horizontal magnetic recording, the older method where magnetization is parallel to the disk surface; perpendicular recording replaced it for higher density.
Compound of 垂直 (perpendicular), 磁気 (magnetic), and 記録 (recording). A direct translation of the English term 'perpendicular magnetic recording'.
