A-2-2 1自由度接触振動計算による軽荷重接触磁気記録の安定性の検討(ヘッド・ディスク・インターフェイス(2),口頭発表)

抄録

In recent years,the light contact recording is proposed in order to reduce the flying height between magnetic head and magnetic disk.But,it is difficult to stably read and write data,because the magnetic head is contacting with magnetic disk rotating at high speed.In this study,we studied the slider vibration in the contact by vibration using 1 degree of freedom model.And,we analytically investigated the effects of the adhesion force between the slider and disk to slider vibration,thickness and viscosity of lubricant layer and roughness of disk surface.As the results,low viscosity lubricant and optimum adhesion force are needed in order to realize the stable light contact recording.
