<p>Disclosed is an intermediate for producing a highly precise light-assisted magnetic head by means of precisely joining an optical element to a slider. By shining light radiating from an autocollimator (AC) onto the lateral surface (IM2c) of a second intermediate (IM2) and detecting the reflected light, the angle of the second intermediate (IM2) is adjusted while displaying the angle of the lateral surface (IM2c) on a monitor (MT). Furthermore, using an alignment mark (WAM) provided to a first intermediate (IM1) as a benchmark, light sources (33) and collimating lenses (34) are sequentially positioned and affixed to the first intermediate (IM1). Afterwards, ultraviolet light is shined through the second intermediate (IM2), a photocurable adhesive applied to a joining surface is cured, and the first intermediate (IM1) and the second intermediate (IM2) are bonded. Furthermore, by simultaneously splitting the first intermediate (IM1) and the second intermediate (IM2) in the shorter dimension at the center of a light focusing reflecting surface (31d) formed on the second intermediate (IM2), it is possible to efficiently produce six light-assisted magnetic heads (3) having a width of w.</p> |
