Abstract
A magnetic card reader for providing an output to a utilization device. A plurality of reed switches are arranged in coplanar relationship in a manner to optimize the number of data sensors in a given area. In addition, a magnetic card is disclosed for providing completely different and independent magnetic data on the opposite surfaces thereby allowing sensing or reading devices to be placed on both sides of the card.
Claims8
A magnetic card reader for reading a magnetized data card adapted to be placed in a predetermined position in said reader, said card having magnetizable points arranged in a predetermined arrangement to permit coding said card by magnetizing certain spots at certain of said points, said reader comprising:
- a base having a flat side,
- a plurality of elongated reed switches supported on said side in coplanar relationship and parallel to said side,
- means for positioning said card parallel to the common plane of said reed switches with the magnetizable points of said card in registration with and closely adjacent corresponding ends of said switches whereby the flux of the magnetized spots actuates the switches corresponding to such magnetized spots,
- said reed switches being arranged in a circular row and radially disposed relative to a common center.
A magnetically encoded card comprising:
- a relatively thin sheet including uniformly distributed magnetizable material,
- a relatively large circular area of the encodable area of said card being magnetized in a direction perpendicular to the faces of said sheet, and
- an encoding magnetized area radially outwardly of said circular area.
