Abstract
An enhanced magnetic head is characterized by sputter induced, micro-texturing yielding rounded globular configurations on slider rail portions. Optimally, this enhanced head is employed in combination with sputter induced micro-textured thin film disk media having a surface or coarseness greater than that of the magnetic head.
