Abstract
A data card is shown. The data card includes a non-magnetic substrate selected from the group consisting of a glass substrate, a glass-ceramic substrate, crystallized glass substrate, an aluminum substrate, a ceramic substrate, a carbon substrate, a silicon substrate and a resin substrate, which substrate, in the preferred embodiment, has a first edge and second edge. A data storage surface region is located on the substrate between the first edge and the second edges. The data surface region includes a magnetic storage medium. A data unit having a combination of a data card and a data card reader is also shown. A method for reading a data storage card is also shown.
