Abstract
A device for reading optical data cards. This device includes a shuttle mounted on shuttle tracks within the device housing. The shuttle is configured to move back and forth on the shuttle tracks driven by the shuttle motor. A card loader allows optical data cards to be positioned onto the shuttle. A CD optical read head mounted on optical read head tracks and driven by a optical head motor reads modified to read a single track of optical card data reads the optical card. A controller receives data from the read head and controls the movement of the shuttle and the optical head.
Claims10
A reader for reading optical cards having optical data tracks flanked on two sides by tracking strips, said reader having a shuttle for holding said optical card and a motor linked to said shuttle such that the optical card can be moved on a shuttle axis, the improvement comprising:
- a CD read head oriented at a CD read head angle such that three illumination beam spots produced by said CD read head are targeted onto a first tracking strip, a targeted optical data track, and a second tracking strip respectively, wherein said CD read head angle is at a different angle than perpendicular to said shuttle axis.
