    • Various embodiments of the present invention provide systems and methods for media defect detection. For example, a data transfer system is disclosed that includes a data detector, a defect detector and a gating circuit. The data detector provides a soft output, and the defect detector is operable to receive the soft output and the data signal, and to assert a defect indication based at least in part on the soft output and the data signal. The gating circuit is operable to modify the soft output of the detector whenever the defect indication is asserted.
    • 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。 例如,公开了一种数据传输系统,其包括数据检测器,缺陷检测器和门控电路。 数据检测器提供软输出,并且缺陷检测器可操作以接收软输出和数据信号,并且至少部分地基于软输出和数据信号来断言缺陷指示。 门控电路可操作以在故障指示被断言时修改检测器的软输出。
