Abstract (en)

[origin: WO9922340A1] A compact data storage device (12) having the approximate dimensions of a credit card that is capable of storing large amounts of data (e.g., 50-100 Megabytes). Moreover, the device (12) may encode data in both a linear magnetic stripe fashion so that the data can be read by typical card swipe data reading devices (e.g., magnetic card swipe devices) as well as optical disc readers that typically read tracks of spirally encoded optical data (40). Additionally, a method for purposefully manufacturing defects into optical discs for authenticating the manufactured optical discs.
