B-2-2 媒質分布を有するディスク面とスライダ間に働くファンデルワールス力の理論解析(B-2 ヘッド・ディスク・インタフェースに作用する相互作用他,口頭発表:ヘッド・ディスク・インターフェイス)

Abstract

Recording media with grooves such as discrete track media (DTM) and bit-patterned media (BPM) are considered to be some of the most promising media for achieving ultrahigh track densities. Thus, it is becoming increasingly important to analyze the static and dynamic characteristics of flying head sliders over DTM/BPM media using the molecular gas-film lubrication (MGL) equation. In this paper, we established an analysis method of van der Waals forces acting between slider and a disk with distribution of material properties by using Fourier series. The characteristics of the van der Waals forces are quantitatively clarified.
