Magnetic cards having a layer being permanently magnetized in a fixed configuration
First Claim
1. An integral magnetic imaging card comprising:
- a pair of opposing major outer sides;
a first visible image fixed on a first of the pair of opposing major outer sides; and
a core underlying at least the first major side, the core including at least a first magnet layer of magnetic material, the first magnet layer having a pair of opposing major sides, and being permanently magnetized in a first fixed predetermined configuration having a magnetically reproducible, other than rectangular first silhouette related at least in informational content to the configuration of the first visible image.

Abstract
Magnetic cards are formed by plural, coadjoining, generally planar, parallel layers. Outermost layers form outer sides of each card. At least a first visible image is provided on a first of the outer sides. The card includes a generally planar, permanently magnetized layer formed by one or more permanently magnetizable planar components that are fixedly positioned preferably within a frame between the opaque outer sides or a magnetizable material layer only -part of which has been selectively permanently magnetized. The permanently magnetized layer or permanently magnetized portion of a larger, magnetizable layer has a predetermined configuration which is related at least in informational content to the first visible image. A silhouette of the predetermined configuration can be magnetically reproduced by placing a card on a magnetically actuated fluid display panel. The permanently magnetized component(s) or magnetized portion(s) of the permanently magnetizable layer generates an image on the panel which has a silhouette identical in configuration to that of the permanently magnetized component(s) or portion(s). Two magnetic layers and two images on opposite outer sides of each card can be provided as well as visible images formed by depressions into the outer surface or cut-outs completely through a card.

35. An integral magnetic card comprising a plurality of coadjoining generally planar layers, at least one of the plurality of layers being a first magnet layer, at least part of the first magnet layer being permanently magnetized material, at least one of the plurality of layers being opaque and overlying a major side of the first magnet layer and being exposed forming a first major outer side of the magnetic card, at least one of the plurality of layers bearing a first visible image on the first major outer side of the magnetic card, and the permanently magnetized part of the first magnet layer having a first magnetically reproducible silhouette other than rectangular in shape and different in appearance from the first visible image yet at least related in informational content to the first visible image.

36. An integral magnetic imaging card comprising:
-
a pair of opposing major outer sides; a first visible image fixed on a first of the pair of opposing major outer sides; and a core underlying at least the first major side, the core including at least a first layer formed at least in part of magnetic sheet material, the magnetic sheet material of the first layer having a pair of opposing major sides, the magnetic sheet material being permanently magnetized in a fixed, predetermined, other than solid rectangular pattern in the first layer, the pattern having a magnetically reproducible, other than solid rectangular first silhouette, the fit silhouette being related at least in informational content to the first visible image on the first side of the card.
