Abstract
Magnetic reading head assemblies are described that enable the alignment of a magnetic reading head to a track of magnetic information on a data card. In addition, embodiments of the present invention can enable the detection of misalignments in circumstances where the elastic mounted magnetic reading head could not aligned with the card reference edge; and therefore, the track of magnetic information on the data card. One embodiment of the invention includes a magnetic reading head including at least one magnetic gap having an alignment axis and a magnetic reading head mount including a base plate. The magnetic reading head is coupled to the magnetic reading head mount, the base plate includes a reference surface substantially parallel to the alignment axis of the magnetic gap and the magnetic reading head is coupled to the magnetic reading head mount in such a way that the magnetic gap of the magnetic reading head aligns with a track of magnetic data on a data card when a length of the reference edge of the data card rests on the base plate.
