Abstract: “Magnetic tape recording is one of the most used systems for information storing due to its reliability and endurance. In these devices, data are transferred from a reading/writing head to a hard disk or flexible tape while a thin layer of air fills the gap between them. Jointly with other factors as the material properties [24,33], the geometry of the gap has a great importance in the quality of the recording. Thus, the hydrodynamic lubrication problem is among the issues that deserve further analysis and precise numerical simulation.“
