Abstract
A new variable rate code with soft-decision decoding has yielded a sto rage capacity of 2 kBytes (30 kbit/in(2)) on a standard banking credit card. The capacity can be further increased through higher track dens ity and using a computationally intensive Bayesian blind inverse filte r. This work is continuing to an estimated 4 kByte (100 kbit/in(2)) ca pacity while remaining compatible with current systems.
