At the time, hard drives used stepper motors, but didn't use microstepping. Paper printers like the MX-80 used stepper motors too, it's true, but didn't use microstepping either. Gearing makes your step size smaller but adds backlash, so it can be the enemy of precision; position feedback like current inkjet printers use is much more precise. |
