Systems and Methods for Reducing Attenuation of Information Derived from a Defective Medium

A system for regenerating data, the system comprising:

• a media defect detector, wherein the media defect detector is operable to identify a potential media defect associated with a medium from which an input signal is derived;
• an attenuation amplitude detector, wherein the attenuation amplitude detector generates an attenuation factor;
• and
• a data detector, wherein the data detector processes a derivative of the input signal augmented by the attenuation factor when the potential media defect is indicated.

• a media defect detector, wherein the media defect detector is operable to identify a potential media defect associated with a medium from which an input signal is derived;
• an attenuation amplitude detector, wherein the attenuation amplitude detector generates an attenuation factor;
• a first data detector, wherein the first data detector processes a null data set when the potential media defect is indicated;
• a decoder, wherein the decoder receives the output of the first detector and provides a soft input based on the output of the first detector;
• and
• a second data detector, wherein the second data detector processes a derivative of the input signal is augmented by the attenuation factor when the potential media defect is indicated.
