Abstract: Magnetic recording media-are provided having separately textured data and read/write head landing zones. Separating these zones on the recording surface allows independent optimization of the topology to maximize both recording characteristics and mechanical durability. The landing or contact start stop zone has an average surface roughness greater than that of the data zone. Preferably, a transition zone extends between the contact start stop zone and the data zone, the transition zone varying between the two in average surface roughness. Preferably, the contact start stop zone is textured first, followed by the data zone, thereby ensuring uniform stiction performance. Texture machines for producing such zone texturing and texturing methods are also provided.
