PROBLEM TO BE SOLVED: To reduce a space for fitting components by disposing a course of movement of a magnetic head adjacently to the middle of one set of phases of driving coils of a spindle motor and also by connecting a noise removing circuit between these phases in one set. SOLUTION: A magnetic head 8 which conducts recording and reproduction of signals for a disk is mounted on a carriage 7 which moves and positions the head in the direction of the radius of a recording medium and is disposed outside a driving coil 4. The carriage 7 is provided with a carriage 10 fitted rotatably in relation to the carriage 7 and the carriage 10 is provided with a magnetic head 9 being opposed to the magnetic head 8. While a capacitor is used for a noise removing circuit in this case, an abrupt current at the time of discharge of the capacitor can be prevented by constructing this circuit out of a series circuit of the capacitor and a resistor and, therefore, a larger effect is produced thereby for suppression of noise. |
