Asymmetrical Dual Capstans
Dual capstans afford good tape isolation, but capstans that rotate at the same speed cause common resonance modes which increase flutter and modulation noise.

Nakamichi has solved these problems and perfected the dual-capstan concept by adopting capstans of different diameters (3 mm on supply, 2.5 mm on takeup.) Further, a unique tape pad lifter removes this major cause of scrape flutter and modulation noise.
