Abstract
A head height adjustment method is for adjusting the height of a magnetic head chip fixed to a free end of an elongated head base extending from a rotary drum. The elongated head base has an intermediate portion bent at first and second restricted areas. A laser beam is emitted on one surface of the elongated head base for bending the elongated head base at the first restricted area to enfold along the first restricted area. Another laser beam is emitted on another surface of the elongated head base, off alignment from said first restricted area, for bending the elongated head base at the second restricted area to enfold along the second restricted area. Thus, opposite end portions of the elongated head base extend parallel to each other, but at different levels.
