    摘要： A manufacturing method of a light source chip for a thermally assisted head comprises steps of (a) providing a light source bar with a surface coating formed thereon; (b) forming several blind holes on the predetermined positions of the light source bar by etching, the blind hole having a top hollowed on the surface coating and a bottom hollowed on the light source bar, and the blind hole having a first biggest width at its top; (c) cutting the light source bar along every two adjacent blind holes by a cutting machine. The cutting machine has a cutting means with a second biggest width that is smaller than the first biggest width of the blind hole, thereby cutting down an individual light source chip without contacting the side edges of the blind hole.

    摘要： To provide a manufacturing method which can adjust the lengths of a recording element and a reproducing element for enabling manufacture of high-quality magnetic head sliders. The manufacturing method comprises: a stacked-layer forming step which stacks magnetic heads on a substrate; a lapping step which cuts out a bar block having a plurality of connected magnetic head sliders, and polishes a flying surface; and a slider cutting step which cuts out individual magnetic head sliders from the bar block. The stacked-layer forming step forms a reproducing-element polish amount detecting sensor on a same layer as that of the reproducing element, and forms a recording-element polish amount detecting sensor on a same layer as that of the recording element. The lapping step carries out polishing based on each output value of the reproducing-element polish amount detecting sensor and the recording-element polish amount detecting sensor.
