1. A system for regenerating data derived from a defective portion of a medium, the system comprising: a data input, wherein the data input is derived from a medium; a media defect detector, wherein the media defect detector provides a defect flag indicating a defective portion of the medium; a data detector receiving the data input and providing a first soft output; a data recovery system receiving the data input and providing a second soft output; and a multiplexer, wherein the multiplexer provides either the first soft output or the second soft output as an intrinsic input based at least in part on the defect flag.
