non-return-to-zero recording; NRZ
A magnetic recording method where the signal does not return to a zero state between bits. Used in early digital magnetic tape and disk storage. The term is technical and primarily encountered in computing history or data storage engineering contexts.
Non-return-to-zero recording was widely used in early magnetic tape drives.
This method is also called NRZ and helped increase data density.
NRZ is the English abbreviation for non-return-to-zero, commonly used in technical documentation. 非ゼロ復帰記録 is the full Japanese term.
磁気記録 is the general term for magnetic recording, while 非ゼロ復帰記録 specifies a particular encoding method.
A compound of 非ゼロ (non-zero), 復帰 (return), and 記録 (recording), directly translating the English term 'non-return-to-zero recording'. The term was coined in the context of early computer data storage technology.
