Systems and methods for low latency media defect detection

A data detection system, wherein the data detection system comprises:nan analog input signal derived from a medium;an analog to digital converter, wherein the analog to digital converter is operable to receive the analog input signal and to provide a series of digital samples corresponding to the analog input signal;a data detector circuit, wherein the data detector circuit is operable to perform a data detection algorithm on the digital sample to provide a detected output, and wherein the data detector circuit is operable to provide an adaptive feedback signal that indicates a difference between the digital sample and the detected output and is used to drive an adaptive feedback loop;a media defect detector circuit, wherein the media defect detector circuit is operable to receive the digital sample, and wherein the media defect detector circuit is operable to determine whether the analog input signal is derived from a defective portion of the medium based in part on the digital sample and to assert a defect output; andwherein the adaptive feedback loop is disabled when the defect output is asserted.

A data detection system, wherein the data detection system comprises:na data detector circuit operable to apply a data detection algorithm to a detector input derived from a medium to yield a detected output, and to provide an adaptive feedback signal indicating a difference between the detector input and the detected output, wherein the adaptive feedback signal is used to drive an adaptive feedback loop;a media defect detector circuit operable to determine whether the detector input is derived from a defective region of the storage medium based at least in part on the detector input, and to assert a defect output where it is determined that the detector input is derived from a defective region; andwherein the adaptive feedback loop is disabled when the defect output is asserted.
