Abstract
Lower cost magnetic recording media and disk drive systems including an improved polymeric or polymeric-based disk substrate are provided by increasing the substrate thickness sufficient to provide mechanical rigidity comparable to that provided by an aluminum-based substrate of similar diameter and forming the CSS zone on the surface of the disk at the outer rather than inner diameter thereof, with a plurality of integrally formed projections extending from the disk surface for reducing heating during head takeoff and landing. The projections are coated with diamond-like carbon (DLC) and lubricant layers for reducing heating and friction during CSS operation and providing good tribological performance when utilized with a cooperating head slider having DLC contact pads.
