Abstract :
A novel data detection scheme is proposed for two-dimensional data storage systems. This scheme is designed to reduce the complexity of two-dimensional Viterbi detector by constraining intertrack interference to be causal and by exploiting the principle of decision feedback. Its application to the two-dimensional optical data storage system is investigated, and further simplifications are also developed.
