Abstract:
A recording/reading-out method of writing and reading data to and from a magnetic disc by a magnetic head by a contact start and stop (CSS) system, wherein the magnetic disc has projections in a CSS region in which the magnetic head conducts a CSS operation, the height of the projections being reduced toward a data recording region of the magnetic disc, said recording/reading-out method comprises the steps of:rising the magnetic head from the magnetic disc, in preparation of performing one of a writing and reading data to and from the magnetic disc, in the CSS region whereat the projections at a height lower than the average height of the projections are present or in the CSS region with no presence of projections neighboring a region in which the projections are present;lowering the magnetic head to the magnetic disc, following performing one of a writing and reading data to and from the magnetic disc, in the CSS region whereat the projections at a height lower than the average height of the projections are present or in the CSS region with no Presence of projections neighboring a region in which the projections are present; andstopping the magnetic head stationary in the CSS region whereat projections each having a height greater than the average height of the projections are present.
