ABSTRACT:
Magnetic data storage media having recording layers that include microscopic surface protrusions are described. A recording head of a magnetic drive may contact the protrusions, i.e., the protrusion tops may define a load bearing surface area of the recording layers of such media. The heights of the protrusions under the recording head and distribution of the protrusions on the recording layers of such media may be substantially uniform. The load bearing surface area may be relatively small when compared to the total surface areas of the recording layers of such media. Also, the average distance between any two adjacent protrusions on such media may be defined based on the length of bits recorded thereon.
