ABSTRACT:
In a head positioning mechanism has a micro tracking actuator which is between a carriage and a supporting spring for making the supporting spring be rotated relative to the carriage to adjust a position of a magnetic head, the micro tracking actuator has a pair of coils held to one of said carriage and said supporting spring. Each of the coils generates magnetic flux in response to a flow of electric current therein. The micro tracking actuator further has a magnet arrangement held to another of the carriage and the supporting spring to face the coil means in a predetermined direction. The magnet arrangement traverses the magnetic flux to have a particular size which varies in accordance with a predetermined relation in response to a relative movement between the coils and the magnet arrangement. The carriage is movably mounted to a magnetic disk device to which the head positioning mechanism applied. The supporting spring is attached to the carriage and rotatable around a predetermined axis extending in the predetermined direction. The supporting spring holds the magnetic head to perform a seeking operation of the magnetic head in cooperation with the carriage.
