摘要： A complementary error evaluator polynomial is generated by obtaining a syndrome polynomial and one or more erasure locations. The syndrome polynomial and the erasure locations are associated with Reed-Solomon encoded information. A complementary error evaluator polynomial and an error locator polynomial are simultaneously generated using the syndrome polynomial and the erasure locations where the complementary error evaluator polynomial is a complement of the error evaluator polynomial.

摘要： A set of one or more samples is received. Using a first signal processor associated with a first phase offset, a first decision and a first error value are generated using the set of samples. Using a second signal processor associated with a second phase offset, a second decision and a second error value are generated using the set of samples. This includes interpolating the set of samples to obtain a set of interpolated samples at the second phase offset and generating the second decision and the second error value using the set of interpolated samples at the second phase offset. A selection associated with the first decision and the second decision is made based at least in part on the first error value and the second error value.

摘要： A length of a separator to be skipped on the storage disk is compared with a threshold. The threshold is associated with a maximum value for which a timing loop is able to be paused without causing the timing loop to have inaccurate timing. If the length is greater than the threshold, a first split sector format is assigned to the split sector and that information is recorded. In such cases, a first portion and a second portion both include synchronization information. If the length is less than the threshold, a second split sector format is assigned to the split sector and that information is recorded. In such cases, the first portion includes synchronization information and the second portion of the split sector excludes synchronization information.
