    摘要: In a hard-disc drive, a defect region on the hard disc is classified as corresponding to either thermal asperity (TA) or media defect (MD) by generating two statistical measures. A first measure (e.g., ∝1) is based on (i) the magnitudes of one or both of signal values (e.g., equalizer input or output signal values) and the corresponding expected values of those signal values and (ii) the signs of one or both of the signal values and the expected signal values. A second measure (e.g., ∝2) is based on the magnitudes of one or both of the signal values and the expected signal values, but not the signs of either the signal values or the expected signal values. The two measures are then compared to determine whether the defect region corresponds to TA or MD.

As an example, a data processing retry circuit is discussed that includes a stepped erasure window register, and an erasure flag set circuit. The stepped erasure window register includes: an erasure flag location, an erasure flag length, and a step size. The erasure flag set circuit is operable to assert a first erasure flag beginning at the erasure flag location and having the erasure flag length at a first time. In addition, the erasure flag set circuit is operable to assert a second erasure flag beginning at the erasure flag location plus the step size, and having the erasure flag length at a second time.
