ABSTRACT:
The frictional coefficient and triboelectric current that exist between the magnetic-head carrying slider and the surface of a magnetic disk when both are in sliding contact are reduced by an appropriate pre-conditioning. The pre-conditioning comprises running the head-disk assembly for at least several minutes at a low velocity of, e.g. 200 to 400 rpm, in a dry gas atmosphere. By this pre-conditioning the lifetime of lubricated head-disk assemblies is increased.
