摘要： An MR head using an MR element as a magnetic detector and having head elements formed on a substrate is provided which comprises a capacitor connected in parallel to the MR element. The substrate is made of a conductive material to serve as one of electrodes forming the capacitor. Owing to this construction, the MR element of the MR head is hardly broken down due to an ESD or EOS.

摘要： The present invention provides a high quality magnetoresistance effect type magnetic head having an increased reproduction output and capable of applying a uniform bias magnetic field to a magnetoresistance effect layer without increasing an impedance. The magnetoresistance effect type magnetic head according to the present invention includes: a magnetic layer 11 magnetized approximately in a vertical direction to a plane 14 opposing to a magnetic recording medium; a non-magnetic insulation layer 12 formed on the magnetic layer 11; and a magnetoresistance effect layer 13 formed on the non-magnetic insulation layer 12 and exhibiting the magnetoresistance effect. In the longitudinal type magnetoresistance effect type magnetic head according to the present, the detection current supplied to a magnetoresistance element is prevented from flowing into a hard magnetic film to lower the head reproduction output.

摘要： A wave plate capable of increasing a birefringence quantity and being made into a thin film, and a method of manufacturing the wave plate. The wave plate includes a substrate, whereon convex portions and concave portions are formed with a period less than or equal to the wavelength of light that is used therewith, columnar portions, wherein fine grains of a dielectric material are layered by oblique vapor deposition of a dielectric material from two directions, in a columnar shape on the convex portions in the vertical direction relative to the surface of the substrate, and interstices that are located on the concave portions and disposed between the columnar portions. Using birefringence from the fine grains of the dielectric material and birefringence from the concave/convex portions of the substrate allows increasing the birefringence quantity and making a thin film.
