Abstract
An apparatus may include a circuit configured to generate a set of first ADC samples based on a first signal associated with a first read head position and a failed segment and to generate a set of second ADC samples based on a second signal associated with a second read head position and the failed segment. The circuit may then generate, by a MISO equalizer, a set of equalized ADC samples based on the set of first ADC samples and the set of second ADC samples.

A system comprising:
- a magnetic disc storage medium;
- a read head array;
- one or more ADC circuits configured to:
- generate a plurality of sets of first ADC samples based on a first signal from the read head array associated with a first read head position of the read head array relative to the magnetic storage medium and a failed segment stored on the magnetic disc storage medium;
