Abstract
A data system (1) includes a credit card type substrate (3) and a data unit (2). The substrate has first and second edges (28, 30) and a data surface region (26) between the edges. The data unit includes a base (4), a substrate support (60) mounted to the base for controlled movement along a first path (14), and a data head driver (6), also mounted to the base, including a data head which reciprocates along a second path (10) oriented perpendicular to the first path. The data head contacts the data surface region on the substrate and first and second data head support surfaces (120, 122) located at opposite ends of the second. path adjacent to the first and second edges of the substrate. The data head support surfaces and the data surface region are coplanar. The data unit also includes a substrate feeder (16), which delivers the substrate to and removes the substrate from the substrate support, and a substrate positioner (68, 70, 82, 94, 98), which properly positions the substrate on and secures the substrate to the substrate support.
