Patent ID: 8902524

Claim:
A method for mitigation of inter-track interference (ITI) in a magnetic recording system, comprising: obtaining ITI cancellation data; and providing said ITI cancellation data for ITI mitigation, wherein said ITI mitigation is performed in combination with an averaging procedure for one or more of (i) ITI mitigation of averaged data samples of a sector obtained by reading a target sector multiple times; averaging the read samples for the target sector over multiple read operations; and mitigating ITI from the averaged read samples to generate ITI mitigated samples; and (ii) averaging a plurality of ITI mitigated data samples of a sector obtained by reading one or more sectors, performing ITI mitigation on at least one sector to generate ITI mitigated samples and averaging the ITI mitigated samples to generate averaged ITI mitigated samples for the at least one sector from multiple read operations.
