装置。[Claims for Utility Model Registration] A pair of actuators that support symmetrical positions with respect to an axis perpendicular to the gap plane of the magnetic head, and a tracking error that outputs the magnetic ↑ tracking error as a detection error signal. a detection means; an azimuth error detection means for detecting an azimuth error of the magnetic head and outputting it as a first azimuth error signal; The first azimuth error signal is calculated by adding the tracking error signal and the first azimuth error signal.
a first addition means for producing an error signal; and a second addition means for producing a second error signal by adding together a second azimuth error signal having an opposite phase to the first azimuth error signal and the tracking error signal. 2, one of the pair of actuators moves the support position of the magnetic head substantially in the tracking adjustment direction in response to the first error signal, and the other actuator moves the support position of the magnetic head in response to the second error signal. A magnetic head position adjustment device characterized by:
