Abstract: A data storage card has an optical data storage region and a magnetic data storage region, and is adapted to cooperatively engage both a drive mechanism of a magnetic stripe reader and a rotatable drive mechanism of an optical data reader. An exemplary embodiment of the card includes a card body defining first and second opposed generally planar surfaces, with an aperture formed in the card body. An annular optical data region centered on the aperture is disposed on one of the first and second surfaces of the card body. At least one magnetic linear data region is disposed on at least one of the first and second surfaces. The card includes an insert structure disposed in the aperture, and configured to engage with the rotatable drive mechanism of the optical data reader in an optical data reading mode, and to engage rollers of the magnetic stripe reader in a magnetic data reading mode. In an exemplary embodiment, the insert structure is a unitary structure fabricated of an elastic material.
