Abstract
This invention relates to azimuth adjustment apparatus for a magnetic head and, more particularly, to azimuth adjustment apparatus for a reproducing head. The azimuth adjustment apparatus for a magnetic head comprises an azimuth adjuster including a control motor to adjust an azimuth of a magnetic head and manual azimuth instruction apparatus including at least one manually variable resistor for generating an azimuth control signal connected to control the motor to vary the azimuth position of the magnetic head in accordance with the resistance value of the manually variable resistor. In case the azimuth adjustment apparatus for the magnetic head is applied to an automatically reversible tape recorder, the manual azimuth instruction apparatus includes forward and reverse variable resistors to be selected in accordance with the direction in which a magnetic tape runs.
