Magnetic sensor for detecting magnetic cards, has multiple rows of magnetoresistive materials that are aligned in direction that intersects at predetermined angle of magnetic card

摘要

The sensor (1) has multiple rows of magnetoresistive materials (3) with the materials in each row being aligned in a direction that intersects at a predetermined angle of a magnetic card. Each material contains a magnetic sensitive region and each material in one of the rows is aligned such that the region in that row overlaps with the region in the next row in the passing direction of the card.
