Support for stabilizing the movement of a magnetic medium over a magnetic head.

摘要

A coupler for a magnetic head includes a flat circumferential surface (18) around the aperture in which the head is mounted and a circumferential orifice surface (19) outside of and adjacent to the flat surface (18). The orifice surface (19) forms a hydrodynamic orifice for control of flow of air over the flat circumferential surface (18) to couple the magnetic medium (11) to the magnetic head (17) by the Bernoulli effect created by movement of air between the medium and the flat circumferential surface. The coupler may protrude through a flat Bernoulli plate (12) against which the magnetic medium, e.g. a magnetic disk, is rotated.
