  • Patent number: 4297570
    Abstract: A stripe for magnetically receiving encoded information; the stripe is bonded and adhered to any type of document having a paper substrate onto which the magnetic stripe is deposited, usually in the form of a narrow rectilinear strip, which is raised above the original surface of the paper substrate by embossing the latter during deposition of the magnetic stripe. Basically the invention entails the provision of a flexible sheet for use in forming a magnetic recording medium in the form of a magnetic stripe on a paper substrate, e.g. a document such as a bank passbook. The sheet includes a first layer of magnetic-particle-free thermoplastic material, which is bonded to the paper substrate by application of high temperature and pressure to a local narrow rectilinear area thereof. Above the first layer and permanently bonded thereto is a middle layer of magnetizable material consisting of a plurality of discrete magnetizable particles dispersed in a matrix.
