Abstract
A magnetic recording head includes a plurality of writers and at least one reader. The plurality of writers and the reader define a plurality of close points of the head. The plurality of writers are spaced apart from one another in a cross-track direction and positioned in the same plane of the head. A plurality of contact sensors are positioned proximate the plurality of writers and the reader. The contact sensors are coupled together and to a pair of electrical bond pads of the head and configured to sense for head-disk contact at each of the close points.
