摘要： A magneto-resitive playback head and a recording and reproducing device for reproducing a recording signal from a double-layered film type perpendicular magnetic recording medium. The playback head includes a magneto-resistive element included in high-permeability thin films and having one end portion facing the recording medium. The magneto-resistive element exhibits a magneto-resistance effect responsive to magnetic fluxes generated from signal magnetization in the recording medium. The head also includes electrodes for supplying an electric current longitudinally of the magneto-resistive element, and high-permeability members for introducing the signal magnetic fluxes passed through the magneto-resistive element again to the recording medium. A magnetic recording and reproducing device comprises the playback head, a thin film magnetic recording head, a recording circuit, a playback circuit, and a driving circuit which gives a relative motion between the medium and the heads.

摘要： A master information carrier comprises a substrate whose surface has an embossed pattern corresponding to an information signal. At least a surface of the protruding portion of the embossed pattern is made of a ferromagnetic material. A method for writing an information signal into a sheet or disk magnetic record medium with a ferromagnetic thin film or coating is performed by putting the surface of the magnetic record medium into contact with the master information carrier so as to write a magnetized pattern corresponding to the embossed pattern of the master information carrier into the magnetic record medium.
