Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: writing a first pattern to a first track on a rotatable storage media and a second pattern to a second track on the media using a write element positioned at a first clearance distance with respect to the rotatable storage media; concurrently using a first read sensor of a multi-sensor transducer to sense the first pattern from the first track and a second read sensor of the multi-sensor transducer to sense the second pattern from the…
