Abstract
Apparatus for sensing data from a magnetic recording medium using a multi-sensor reader with different readback sensitivities. In accordance with some embodiments, a data transducing head has first and second read sensors. The first read sensor is optimized for reading data and the second read sensor is optimized to detect thermal asperity (TA) events.
