摘要： In the magnetic recording characteristics of recording apparatus, when there are three or more magnetic tips disposed on one head base, the extension lines in the depth direction of the head tips pass through the central line of the cylinder. The both outermost head tips on the head base disposed in one window of the cylinder possess head gaps as dummy head, but do not have the function of magnetic recording characteristics of recording, reproducing and erasing. In the disclosed multiple magnetic head, the materials of the head tips on one head base including the dummy head are the same.

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.
