The present invention discloses a fluid bearing amount to rotatably support an impelled rotatable spindle having smooth support surfaces. Each bearing includes a stationary housing supporting a bearing annular track representing a continuous and soft support surface which is disposed in the direction of a complementary support surface of the spindle; the track and spindle define together an even, narrow and continuous groove space. The smooth track support surface is interrupted by a plurality of radially separated pressure generating zones, each being capable of dynamically compressing a fluid body contained in a portion inside the groove, at any spindle rotation direction, at high speeds. The pressurized fluid is supplied so as to flow through each zone and outside the groove, while a predetermined hydrostatic force is exerted against the spindle at lower rotational speeds.
