  • Patent number: 6057978
    Abstract: A disk driving device is provided with a stepping motor arranged to move a head in units of a predetermined step with respect to a disk-shaped recording medium and a driving pulse generating circuit arranged to generate driving pulses for driving the stepping motor on the basis of a step pulse signal supplied from a host computer. The driving pulse generating circuit is arranged such that, the driving pulse generating circuit outputs, to the stepping motor, driving pulses obtained by delaying, by a predetermined length of time, step pulses occurring sequentially in the step pulse signal, if the step pulse signal is supplied at intervals of time less than a predetermined period of time, and outputs, to the stepping motor, driving pulses obtained without delaying the step pulse signal if the step pulse signal is supplied at intervals of time not less than the predetermined period of time.
