Disk drive margining read channel using predictable disturbance samples generated as a function of a written pattern
Abstract:
A disk drive is disclosed comprising a head actuated over a disk having a plurality of tracks. A pattern is read from the disk to generate a read signal, and the read signal is sampled to generate read samples. Predictable disturbing samples are generated as a function of the pattern. The predictable disturbing samples are added to the read samples to generate disturbed samples, and a data sequence is detected from the disturbed samples.
