<p>MAGNETIC INFORMATION AND CARD READER SYSTEM AND CARD READER FOR READING MAGNETIC-TYPE INFORMATION CARDS Disclosed herein is a magnetic information card and card reader system, as well as a card reader for reading information magnetically recorded on a flexible resilient magnetic card. The system includes a flexible, resilient magnetic information card having a flexible base layer, a flexible over layer of nonmagnetic material and a layer of uniformly distributed magnetic particles of lesser dimensions sealed between the base and over layer such that the magnetic particle layer is spaced from all edges of the card, and a card reader having a magnetic reading head for detecting magnetic signals on the magnetic layer. The card reader has a structural portion forming a slot accommodating the information card in a tight but not binding fit. The structural portion supports the reading head in a position such that the gap end of the reading head projects into the slot an appreciable distance. The structural portion also has a hole forming a relief opposite the reading head to accommodate the localized region of deformation of the card which is formed when the card is forced past the reading head. Also disclosed is a card reader for reading information magnetically recorded on a flexible resilient magnetic information card. The reader has a slot adapted to receive the card as it is manually inserted into the slot and a magnetic reading head disposed such that its magnetic gap end extends appreciably into one side of the slot. A relief hole is disposed on the other side of the slot and at a point opposite the gap end of the reading head, the relief hole having a dimension at least as great as the reading head in the direction of travel of the card.</p> |
