In a magnetic recording and/or reproducing apparatus, it is necessary to adjust the height of each of a plurality of magnetic heads carried by a rotary cylinder for movement together therewith. This adjustment is accomplished by rotating an optical axis of a laser beam emitted from a laser oscillator in synchronism with the rotary cylinder so that the optical axis is always maintained stationary relative to the magnetic head. The laser beam is subsequently irradiated to a head base in the proximity of a head chip secured to the head base, thereby adjusting the head height during rotation of the rotary cylinder.

Title
