Abstract: PROBLEM TO BE SOLVED: To realize low load torque and high rigidity by controlling the temperature of a fluid bearing, which supports a spindle motor, in a proper range against change in ambient temperatures in use. SOLUTION: While a spindle motor 2 or a magnetic head arm mechanism 3 among others are assembled in a base 1, a magnetic disk 5 mounted on a cassette case 4 is rotatably driven by the spindle motor 2, with various pieces of information recorded and reproduced by a magnetic head 6. The spindle motor 2 is provided with a fluid bearing 22, in proximity to which a Peltier 10 element and a temperature sensor are installed. Then, by discriminating temperature in the fluid bearing 22 with the temperature sensor and comparing it with a prescribed set value, the polarity and level of an applied voltage are controlled for the Peltier element 10, so that the temperature of the fluid bearing 22 is controllably maintained in a specific range.
