Magnetic card reading in the presence of noise

Keywords:magnetic read head? key parameters? data sheets?

Most magnetic read head data sheets do not fully specify the frequency-dependent components and are often vague when specifying other key parameters. In some cases, the specifications of two very similar heads from two different manufacturers might be quite different in terms of parameters specified and omitted. The limitations in the data sheets make designing an optimum card reading system unnecessarily difficult and time consuming. This document outlines a strategy to overcome the above shortcomings and offers guidelines to overcome the noise issues.
