초록 ▼

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.

A magnetic head installed drum unit for use in a magnetic recording/reproducing device, comprising: a rotary drum having a first open through hole defining an axis therethrough; a fixed drum coaxially located adjacent said rotary drum and having a second open through hole defining an axis therethrough; a head chip having a gap for writing/reading data on a magnetic recording medium which moves past said head chip by contacting said magnetic recording medium; and an elongate head base extending lengthwise between said first open through hole of said rotary drum and said second open through hole of said fixed drum and having a first end fixed to said rotary drum and a second end holding said head chip, said elongate head base further having spaced apart, along a length thereof, first and second plastic deformations intermediate said first and second ends, said first plastic deformation being located at a position in alignment with said axis of said first open through hole, and said second plastic deformation being located at a position in alignment with said axis of said second open through hole, wherein a first horizontal length of said elongate head base between said first end and said first plastic deformation and a second horizontal length of said elongate plate between said second end and said second plastic deformation extend normal to a rotary axis of said rotary drum and parallel to each other at different vertical levels, said first and second plastic deformations having been thermally formed by exposure to laser beams through said first and second open through holes on opposite surfaces of said elongate head base so as to plastically deform said elongate head base at positions on said opposite surfaces exposed to said laser beams.
