The present application discloses a transducer head comprising a read element that reads data from a storage media and an asperity sensor that detects a dimension of an asperity on a surface of the storage media using a temperature change at the asperity sensor. The asperity may be one or both of a void in the surface of the storage media and a protrusion from the surface of the storage media.
