The present invention provides a manufacturing method of a magnetic recording medium capable of reducing the deterioration of a recording layer and improving the Duty cycle of the recording layer. An embodiment of the present invention is a manufacturing method of a patterned recording medium such as BPM (Bit Patterned Media) and DTM (Discrete Track Media). The manufacturing method has a deposition step of depositing a resist protective film on a resist pattern formed on a workpiece containing a recording layer, and a recording layer processing step of processing the recording layer into a pattern shape by dry etching using the resist pattern and the resist protective film as a mask.
