This article describes a method to improve the spindle speed settle time in a variable-track-format (VTF) flexible disk drive having different spindle speeds for each track. The method consists of increasing the rate at which track access commands are sent across the interface to the drive. This results in a shorter rise-time signal, that is, a signal which is a better approximation to a step than to a ramp at the input to the spindle speed controller.
