Abstract
A method of manufacturing a recording medium includes the steps of: a) providing an underlayer on a substrate; b) providing a magnetic layer on the under layer; c) providing a protection layer of amorphous carbon on the magnetic layer; and d) providing a lubrication layer of fluorine on the protection layer, the lubrication layer including a bonding layer part which is strongly bonded to the protection layer and a mobile layer part which is not strongly bonded to the protection layer. The method further includes the steps of: e) implementing a UV curing process on the surface of the protection layer between the step c) and d), so that a ratio of the bonding layer part in the lubrication layer is increased.
