A magnetic recording medium is a magnetic card. It consists of high-strength, high-temperature plastic or plastic coated paper, to moisture, abrasion and there is a certain degree of flexibility, easy to carry, use of more stable and reliable. Typically, the magnetic side is printed with instructions prompted information, such as card direction; the other side there magnetosphere, or magnetic stripe, with 2-3 tracks to record information about the data. Magnetic stripe manufacturers can supply a variety of color stripe according to market demand, such as gold, silver, red, green, blue, brown, black. Reasons magnetic stripe showing different colors, in the standard magnetic stripe coated protective layer of the desired color result. Currently, standards-compliant magnetic read and write magnetic device can be of different colors magnetic stripe read and write magnetic, so the color does not affect the normal magnetic stripe magnetic read and write magnetic. Can normal magnetic magnetic stripe read and write magnetic and electromagnetic properties primarily closely, including the slope of the saturation curve, the signal amplitude, resolution, and take the pulse of erasable. Magnetic stripe by three tracks: the alphanumeric tracks - the first track; digital tracks - the second track; read and write tracks - the first three tracks, a sign of its good or bad the quality is mainly composed of the signal amplitude, pulse and can take erasure of the composition, in accordance with national and international standards, to measure the signal amplitude, pulse and erasable sexual risk indicators is a relative ratio of the data.
