Abstract: PURPOSE:To keep the floating height constant, and also, to reduce an uneven rotation by providing a means which is positioned in the periphery of a fixed center shaft and displaces a thrust supporting piece of a dynamic pressure bearing of head loaded rotating body, in the height direction, and controls a head position. CONSTITUTION:A vibration of a piezoelectric body 8 is amplified and synthesized by utilizing a resonance characteristic of a vibrating body 9, a traveling wave being concentrical with a fixed shaft 1 and in the peripheral direction is generated on the surface which is brought into contact with a thrust supporting piece 7, and a rotating body 2 is started. The rotating body 2 rotates as one body with the supporting piece 7 by an attraction force of a rotor magnet 3 and a stator yoke 6, and a frictional force on the surface 20 caused by a thrust load. When it reaches the number of revolution n1, a counter electromotive force is generated in a coil 5 by the magnet 3. By detecting it, feed is executed to the coil 5, and the rotating body is further accelerated. When the rotating body 2 rotates at a high speed, a lubricating fluid 15 flows at a high speed in grooves 11, 11' on the surface of the shaft 1 and in a groove 12 on the supporting piece 7, and floats the rotating body 2. According to such a constitution, the height of a head is kept constant, and the uneven rotation can be reduced.
