The present invention is a manufacturing method of improving the
signal-to-medium noise ratio of a magnetic media disk through closer
head-to-media spacing, and the resulting disk, by evenly lubricating a
magnetic media disk, increasing the viscosity of a selected region of the
disk, and removing at least a portion of the lower viscosity region of
the lubrication layer, thereby decreasing the thickness of the
lubrication layer in the portion of the lower viscosity region, producing
a magnetic media disk capable of closer head-to-media spacing in the
portion of the lower viscosity region of the lubrication layer.
