Abstract:
1. A method of manufacturing a magnetic disk having a substrate, a magnetic layer, a protecting layer and a lubricating layer on the substrate, comprising the steps of: forming the magnetic layer and the protecting layer sequentially on the substrate; and immersing the substrate on which the magnetic layer and the protecting layer are formed in a solution containing a hydrocarbon-based silane agent or a partial fluorinated hydrocarbon-based silane agent, thereby forming a lubricating layer on the protecting layer; wherein the hydrocarbon-based silane agent is represented by the following general formula (I): wherein R represents a hydrogen atom, an alkyl group or a halogen group; and n represents an integer from 3 to 20; and the partial fluorinated hydrocarbon-based silane agent is represented by the following general formula (II): wherein R represents a hydrogen atom, an alkyl group or a halogen group; and n+m represents an integer from 3 to 20.
