A recording device comprising: a recording medium; a motor that drives the recording medium; a head that records and reads out a signal to and from the recording medium; a vibrating plate that has two opposing surfaces facing the recording medium, the vibrating plate being displaced in a rotation axis direction of the recording medium; and an oscillator that is positioned away from the two opposing surfaces of the vibrating plate facing the recording medium, the oscillator driving and displacing the vibrating plate; wherein the vibrating plate has two plate-like structures; wherein, when the oscillator displaces the vibrating plate, the two plate-like structures of the vibrating plate are displaced at a same frequency in the rotation axis direction of the recording medium; and wherein vibration phases of the two plate-like structures are 180 degrees apart in an opposite phase mode.
