摘要： A magnetic head device includes a rotary cylinder and a magnetic head having one end fixed to an inner portion of one surface of the rotary cylinder such that the magnetic head extends from the inner portion toward the outer circumference of the rotary cylinder in alignment with a radius thereof. The head tip is provided on another end of magnetic head. A laser beam is impinged on the base plate at a portion within a range from 2 mm to (5.times.T1/2)mm from the outer edge of head tip where T is a thickness of the bass plate. The portion on which the beam impinged is heated and melts causing the base plate to incline in a vertical direction which is parallel to an axis the rotary cylinder. Thus, the head tip is positioned at a required horizontal level which is perpendicular to the axis of the rotary cylinder.

摘要： 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.

摘要： 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.

摘要： A vibratory actuator includes a piezoelectric element, a driver element provided on the piezoelectric element and a movable body supported by the driver element. A control unit supplies a first voltage and a second voltage at the same frequency to the piezoelectric element. By supplying the first voltage and the second voltage having a difference phase from a phase of the first voltage by 90°, the piezoelectric element is lead to composite vibration of stretching and bending, thereby causing the driver to make an elliptical motion by the vibration and move the movable body. The control unit switches, during a fine mode, a phase difference between the first voltage and the second voltage between 90° and 0°.
