There is provided a magnetic recording/reproducing apparatus which has an improved reliability for a reproduced signal by eliminating a deformation in a reproduced signal waveform due to a residual magnetization generated in a magnetic head. The magnetic recording/reproducing apparatus has a magnetic recording medium including a magnetic film to which information is magnetically recorded and a thin-film magnetic head including a magnetic pole and a coil provided around the magnetic pole. A current supplying circuit supplies a current to the coil so that a magnetic state of the magnetic pole is stabilized. The current is supplied to the coil after a recording operation has been completed by the thin-film magnetic head. The current may demagnetize the magnetic pole of the magnetic head, or stabilize the magnetic state of the magnetic pole.

An apparatus for ejecting droplets of ink including: a passage for ink; an orifice disposed at one end of the passage; a pressure-applying device for applying a pressure wave to the ink within the passage; and a signal-supplying device for supplying an actuating signal to the pressure-applying device. The frequency of the signal is such that the displacement of the ink surface at the orifice due to the pressure wave is maximized.
