The CSS performance for lightly textured disks

In this paper, the CSS performance for lightly textured disks with various topographical parameter was investigated. Four kinds of topography were textured on the disks with different texturing parameters on which high frequency surfaces were created.

Summary

In the continuing pursuits of ever-higher magnetic recording areal density, the texture design of the disk. has became very crucial in reducing the flying height of the magnetic head. As the flying height approaches the near contact regime (~1 Onm), the traditional laser bump approach is no longer feasible and a smoother disk surface is beneficial to achieve excellent tribology performance for recording density greater than lOGIfin² [1]
