  • Patent number: 9305596
    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.
