    摘要: A magnetic domain controlling film for controlling the magnetic domain of a magnetoresistive film is formed by a patterning technique on a lower insulating film formed on a lower shield film. The magnetoresistive film is formed on the magnetic domain controlling film for converting a magnetic signal from a magnetic recording medium into an electrical signal using the magnetoresistive effect. A resist pattern is formed by the lift-off method on the magnetoresistive film in such a fashion as to leave a region of the magnetoresistive film corresponding to the tracks of the magnetic recording medium. A magnetoresistive element is formed by ion milling leaving only the portion of the magnetoresistive film corresponding to the tracks. An insulating layer is formed on the resist pattern, on the upper surface region of the lower insulating film other than the portion thereof right under the magnetic domain controlling film reduced in thickness by ion milling, and on the upper surface region of the magnetic domain controlling film other than the portion thereof right under the magnetoresistive film. An electrode film is formed on the insulating layer, after which the resist pattern is removed. The insulating layer is contiguously deposited on the upper surface region formed in a thin layer of the lower insulating film and on a part of the upper surface region formed in a thin layer of the magnetic domain controlling film.

    摘要: A laser light flux is divided and synthesized so that its light intensity distribution is changed from a Gaussian distribution to a non-Gaussian distribution. When a laser light flux having a Gaussian distribution is irradiated onto a dividing prism, it is divided into a left part and a right part which are refracted right and left inversely from each other. When the right and left parts are incident on a synthesizing prism, they are refracted again and travel to be overlapped with each other on a recording medium. The light intensity distribution on a segment at the apex of the synthesizing prism is weaker at the central part and stronger at the peripheral part. This is because the light fluxes resulting from the division are inverted in their position so that the central part of the Gaussian distribution is separated left and right while the peripheral part with a weaker light intensity is centered.
