Patent ID: 7084536

Claim:
A fluid bearing motor comprising: a hollow cylinder passed through via axis of rotational center; a flange formed at one end of said hollow cylinder; a rotor section provided with a rotary magnet disposed on outer bottom of said flange; a rotary bearing member configured with an outer cylinder surface of said hollow cylinder and a bottom end of said flange; a chassis; a generally cylindrical fixed bearing member secured to said chassis and configured with an inner cylinder surface supporting said hollow cylinder so as to be rotatable via a small first radial space and a plane supporting an inner side bottom end of the flange so as to rotate in an axial direction at upper surface of said plane; a hydrodynamic lubricant filled between said fixed bearing member and said rotary bearing member; a fixed shaft with one end fixed on the chassis, which passes through the hollow cylinder via a second radial space wider than said first radial space; and a stator provided with a coil which generates a rotational force in cooperation with the rotary magnet.
