  • Method for reading magnetic data
    Publication number: 20090046393
    Abstract: A method of reading magnetic data from a magnetically-activatable sheet product carrying magnetic data. The product comprises a pair of laminated outer sheets between which is a magnetic layer comprising magnetically-activatable particles in a binder matrix. For reading the data, a thin-film magnetoresistive sensor is used in which the shape anisotropy of the sensor is enhanced in a direction transversely to the longitudinal axis of the sensor.
