Abstract
A method for making a credit card (or other type of data storing card) comprising a magnetic strip includes the step of depositing a magnetic recording layer on a substrate, cutting the substrate into strips, and mounting the strips onto the credit card. In one embodiment, the strips comprise glass that is sufficiently thin to be bendable. The magnetic recording layer is sputtered onto the glass using a high temperature sputtering apparatus. In another embodiment, the substrate is a metal foil. The data recording capacity of the magnetic strip is greater than that which can be achieved by using particulate media.
