CPC classification number: G11B5/6041 , G11B5/3133
Abstract: A media-facing surface of a magnetic head is positioned proximate a moving magnetic recording medium. A current is applied to an electromagnet of the magnetic head. The current induces a magnetic force between the magnetic head and the magnetic recording medium that adjusts a clearance therebetween.
Abstract translation: 磁头的面向介质的表面位于移动磁记录介质附近。 电流施加到磁头的电磁体。 电流在磁头和磁记录介质之间引起磁力，从而调整它们之间的间隙。
