Abstract: The recording medium is formed from four layers. The layers are formed on a non-magnetic material which forms the structural part of the disc or tape. There are two layers which are formed on top of the non-magnetic base. The layer immediately on top of the base is a non-magnetic layer which is formed by dispersion of a non-magnetic powder in a bonding agent. A second layer is formed over this layer to form the outer surface of the recording medium. This layer is formed from magnetic particles in a bonding agent. The underside of the base also carries a bottom magnetic layer, similarly formed. The top magnetic layer carries the data, the bottom layer makes the field distribution uniform.

Abstract: PROBLEM TO BE SOLVED: To provide an electrode film excellent in productivity and having a highly durable electrode layer, a manufacturing method thereof, and a coordinate input device using the electrode film. SOLUTION: The electrode film 1 includes a substrate 2, a low elasticity layer 3, a high elasticity layer 4, and an electrode layer 5. The low elasticity layer 3 is laminated on the substrate 2, consists of a first material as a liquid curable material, and has a first elastic modulus. The high elasticity layer 4 is laminated on the low elasticity layer 3, consists of a second material as a liquid curable material, and has a second elastic modulus larger than the first elastic modulus. The electrode layer 5 is laminated on the high elasticity layer 4, and consists of a conductive material. When the electrode film 1 is depressed, the low elasticity layer 3 acts as a cushion, and the high elasticity layer 4 prevents local deformation of the electrode film 1, thereby preventing a breakage caused by distortion from occurring in the electrode layer 5. Further, the low elasticity layer 3 and high elasticity layer 4 can be laminated by coating. COPYRIGHT: (C)2011,JPO&INPIT
