ABSTRACT:
A drive signal generating device for outputting a pulse signal to a spindle motor for driving a magnetic disk, to thereby rotate the motor in accordance with the pulse signal. The rotational speed of the motor is determined by the pulse width and pulse period of the pulse signal. The amplitude of the pulse signal is lowered as the source voltage of a power source is lowered, and the pulse period is shortened as the source voltage is lowered.
