  • Patent number: 3990106
    Abstract: A dynamic pressure type floating head system comprising a floating magnetic head, a magnetic recording medium which stores information to be recorded and a resilient member for supporting the magnetic head. The floating head comprises a first flat surface portion of a sliding surface and a second flat surface portion having embedded therein a plurality of projections on the same plane. The attractive force caused by the viscous flow generated between the first surfaces by the relative movement of the surface to be recorded is combined with the holding force caused by the slip flow generated between the second surfaces so that the floating gaps are narrowed.
