ABSTRACT:
A driving circuit for driving a pulse motor so as to move a head for a floppy disc supplies power to two phase coils using first applying means for directly applying the voltage of the power source to the phase coils while the head is moved, and second applying means for dividing the voltage of the power source to substantial halves by connecting the phase coils in series and for applying the substantial half of the voltage into each of the phase coils while the head is stopped during a waiting mode.
