Writing Balance Rule: Keep the left radical (钅) compact and narrow, leaving enough horizontal space for the right phonetic component (氺/录 parts) to expand without crowding.
Simplification Logic: The traditional form 錄 uses the tree/metal radical and complex internal elements, which were streamlined into the metal radical on the left and a simplified right component in the modern character 录.
