| 1. A spindle motor structure comprising:
a spindle motor installed on a base and having a hydrodynamic bearing supporting a shaft which is operative to rotate using
hydrodynamic pressure and a driving source rotating the shaft using an electromagnetic force;
a circuit board installed to face the base and which supplies driving power to the driving source; and
a heater installed on the circuit board at a position facing the hydrodynamic bearing and which heats the hydro dynamic bearing;
wherein the heater comprises:
a heating portion which receives current and generates heat;
an insulation body arranged between the heating portion and the circuit board and for insulating the transfer of the heat
generated from the heating portion to the circuit board; and
a connection terminal electrically connected to the circuit board.
