record
録 centers on capturing and preserving information: making a record, writing something down, or registering it so it can be kept.
録 combines 金 (metal) with 录, which likely contributes the sound and the idea of carving or inscribing records into metal.
Metal 金 was used to carve lasting records. The right side 录 looks like a stylus pressing into a surface, together making a permanent record.
For ロク, imagine a record locked in a metal safe: lock -> ロク, and the metal safe keeps the record secure.
