Abstract: Read channel circuitry comprises a decoder and error correction circuitry. The error correction circuitry is configured to calibrate a first set of filters using a read channel data signal, to determine first hard decision information regarding the read channel data signal using the calibrated first set of filters, to determine an error corrected read channel data signal using the first hard decision information, to calibrate a second set of filters using the error corrected read channel data signal, to determine second hard decision information regarding the error corrected read channel data signal using the calibrated second set of filters, and to decode the second hard decision information. The first set of filters and the second set of filters are calibrated in respective first and second calibrators.

Abstract: A method for producing a LDPC encoded test pattern for media in a LDPC based drive system includes adding error detection code data to a predominantly zero bit test pattern and adding additional zero bits to produce a test pattern of a desirable length. The test pattern may then be scrambled to produce a desirable flaw detection test pattern. The flaw detection test pattern may then be encoding with an LDPC code, or other error correction code with minimal disturbance to the run length constraints of the data pattern, and written to a storage medium.
