    • A magnetoresistance effect thin-film magnetic head superior in magnetic stability and capable of developing a high playback power. The thin-film magnetic head has a magnetoresistance effect stabilizing layer 11 inclusive a diamagnetic film or a hard magnetic film, a non-magnetic insulating layer 12 and a magnetoresistance effect layer 13 inclusive of a magnetoresistance effect film, layered together to form a magnetoresistance effect element 3. The thin-film magnetic head also has a non-magnetic insulating layer 4 arranged on a lateral surface of the magnetoresistance effect element 3 and a pair of electrodes connected to the magnetoresistance effect layer 13 on both ends of the upper surface of the magneto-resistance effect element 3. The playback signals are detected by the magnetoresistance effect of the magnetoresistance effect layer 13.

    • A phase difference element capable of reducing reflection of incident light and a manufacturing method for the phase difference element are disclosed. The phase difference element includes a transparent substrate 11, an interface anti-reflection film group 12 and an obliquely vapor deposited film 13. The interface anti-reflection film group is composed by one or more of alternately high and low refractive index films, with the film thicknesses of the respectively films being equal to or less than the wavelength of light in use. The obliquely vapor deposited film is formed by a plurality of layers of a dielectric material. These layers are alternately obliquely vapor deposited from two directions differing by 180° from each other. The refractive index of the interface anti-reflection film group 12 is higher than the refractive index of the transparent substrate 11 and lesser than that of the obliquely vapor deposited film 13.
