Abstract

Methods, systems and computer program products for performing hybrid defect detection are disclosed. A hybrid defect detection mechanism may be used to detect various classes of defects (e.g., long and shallow defects, and short and deep defects) while reducing the probability of a miss or false alarm. In some implementations, the hybrid defect detection mechanism may utilize defect detectors to each receive signal samples and apply a different set of parameters indicating a different respective window to the signal samples. Each defect detector may generate a corresponding output based on a count of signal samples within the corresponding window that are associated with abnormal signal quality.
