Abstract: Apparatus and method for detecting media defects using a multi-sensor transducer. In some embodiments, a first pattern is written to a first track on a rotatable storage media and a second pattern is written to a second track on the media. A first read sensor of a multi-sensor transducer senses the first pattern from the first track and a second read sensor of the multi-sensor transducer concurrently senses the second pattern from the second track. At least one storage media defect is detected responsive to the sensed first and second patterns.

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.
