Skew-tolerant multiple-reader array in array-reader based magnetic recording
Abstract:
A method for enhancing read performance in an ARMR system includes: obtaining CTS information for a plurality of readers in a multi-reader head of the ARMR system, the CTS information defining a relationship between skew angle and CTS between respective combinations of subsets of the readers; determining, as a function of the CTS information, a subset of the readers which provides enhanced read performance among the readers for each of a plurality of skew angles; assigning a weight value to each of a plurality of read signals generated by a corresponding one of the readers for each of the skew angles, the weight value being indicative of a performance of the corresponding one of the readers relative to one another; and decoding information read from at least one target track of a magnetic storage medium being read as a function of the read signals and corresponding weight values.
