non-return-to-zero (change) recording; NRZ(C)
A magnetic recording method in which a change in magnetization represents a binary 1, while no change represents a 0. Used in early digital magnetic tape and disk storage.
Non-return-to-zero change recording was widely used in early magnetic tape drives.
NRZ (non-return-to-zero) recording without the change variant; a related but distinct encoding method.
A direct translation of the English computing term 'non-return-to-zero change recording', composed of 非 (non-), ゼロ (zero), 復帰 (return), 変化 (change), and 記録 (recording).
