  • Abstract
    An upper bound is derived for the SNR merits that may be attributed to run-length-limited codes when used in high-density recording systems with optimum mean-square decision feedback equalization. It is argued and exemplified that these merits often lag behind the SNR improvement that uncoded storage would bring about via a reduction of the signaling rate. Losses are quantified for a number of practical codes as well as for maxentropic (d,k) sequences
