发明名称 Thin-film magnetic head having near-field-light-generating portion with trapezoidal end
摘要 A thin-film magnetic head for a heat-assisted magnetic recording which can perform a reliable writing immediately only on a desired track by applying a near-field light to a desired position and range is provided. The head comprises: an electromagnetic coil element for writing data signals, having a pole end reaching a head end surface; and a near-field-light-generating portion for heating a portion of a magnetic recording medium during write operation by generating a near-field light, having a generation end reaching the head end surface and provided adjacent to the pole end and in the leading side of the pole end, and a shape of the generation end on the head end surface being a trapezoid with a shorter edge on the trailing side, or being a triangle with an apex on the trailing side and with a bottom on the leading side.
