For demands of high-density recording with a high data transfer rate, various recording head shapes were designed to achieve the low tape surfacing. The momentum equation for a tape of finite length is coupled to the transient lubrication equation for the air film between the tape and the recording head. If ditches exist on the recording head, it is necessary to use the fluid equations. In this paper, we introduce an analysis approach with connecting the fluid equations in a ditch and the lubrication equation in narrow space by these boundaries.
