Abstract
Magnetic patterned media comprise topographical features readable with a slider-mounted non-magnetic transducer sensitive primarily to a local aerodynamic boundary condition, in addition to a magnetic recording layer substantially conforming to the topographical features. Passage of a transducer over the features generates effects that can be detected in, and separated from, the magnetic recording signal.
