    摘要： A magnetic recording medium has a picture formed by a picture forming reagent in a layered body formed by a plurality of layers including a basic layer and a magnetic recording layer. The picture can be recognized from a surface of the direction opposite to the basic layer of the layered body. The picture forming reagent is distributed in the film thickness direction and has a region having a concentration gradient gradually decreasing toward the direction of the magnetic recording reading side from the center portion of the magnetic recording layer in the region of the read side from the center portion of the magnetic recording layer in the layered body.

    摘要： A magnetic card having a magnetic recording layer and a print layer on the recording layer with less output variation, a transfer magnetic tape having a pattern on a magnetic stripe with less output variation even when the tape is provided on a card, and a method of producing such a tape are disclosed. The card comprises a card base, a magnetic recording layer on the card base, and a print layer on the recording layer. The print layer includes a pattern print region and a region where a filled layer other than the pattern print region is provided, and has a substantially uniform thickness. The transfer magnetic tape comprises a support film and layers formed on the film in multilayer and including a print layer, a magnetic recording layer, and an adhesive layer in order of mention from the film. The print layer includes a pattern print region and a region where a filled layer other than the print region is formed, and has a substantially uniform thickness. The method comprises forming a pattern print region on a support film, forming filled layer in a non-print region in such a way that a print layer made up of the pattern print region and the filled layer has a substantially uniform thickness, and forming a magnetic recording layer and an adhesive layer on the print layer.

    摘要： A magnetic recording medium comprising a magnetic recording layer, an intermediate layer, and a masking layer which are successively formed on a non-magnetic supporting body made of a thermoplastic resin. The magnetic recording layer and the intermediate layer are buried inside a part of the non-magnetic supporting body, the surface of the intermediate layer is smoothly flash with the surface of the non-magnetic supporting body, and the masking layer masks the surface of the intermediate layer and the surface of the non-magnetic supporting body. The masking layer of the magnetic recording medium has an excellent masking capability and an adhesion to the magnetic recording layer, and high design property irrespective of the kind of magnetic particles used for the magnetic recording layer.
