    • Various embodiments of the present invention provide systems and methods for media defect detection. As an example, a data processing circuit is disclosed that includes a defect detector circuit and a comparator circuit. The defect detector circuit is operable to calculate a correlation value combining at least three of a data input derived from a medium, a detector extrinsic output, a detector intrinsic output and a decoder output. The comparator circuit is operable to compare the correlation value to a threshold value and to assert a media defect indicator when the correlation value is less than the threshold value.
    • 本发明的各种实施例提供了用于介质缺陷检测的系统和方法。 作为示例,公开了包括缺陷检测器电路和比较器电路的数据处理电路。 缺陷检测器电路可操作以计算组合从介质导出的数据输入,检测器外在输出,检测器本征输出和解码器输出中的至少三个的相关值。 比较器电路可操作以将相关值与阈值进行比较,并且当相关值小于阈值时断言介质缺陷指示符。
