摘要：
This paper reports authors' efforts in slider and interface technologies with extremely small and very high stability head-disk spacing. The dual shallow step strategy is proposed in the femto form-factor slider design. It is found that the dual shallow step design is very effective in reducing flying height modulation (FHM) caused by disk waviness and enhancing the cooling effects on the read/write elements. A simple geometric model is built to explain the schematic of the improvement in FHM. (c) 2006 Elsevier Ltd. All rights reserved.
