Claims

[Scope of utility model registration request]

The magnetic head is provided with a rotating shaft that is installed approximately at the center of the recording/playback track width and rotatably supports the magnetic head, and a piezoelectric element that rotates the magnetic head around the rotating shaft. An azimuth adjustment device for a magnetic head, characterized in that the piezoelectric element is driven by the detection output of the magnetic head to rotate the magnetic head and correct an azimuth error.
