Abstract
A method for making a data card involving photolithographically prerecording information, such as reference position information or servo tracks, on a strip of high resolution, direct-read-after-write laser recording material, then adhering the strip to a card such that the strip is recordable in place. A protective transparent laminating material is bonded to the recording surface and then user information is recorded on the strip using a laser aimed at the strip through the laminating material.
