A method of producing a magnetic recording medium and a production device therefore capable of producing a discrete type magnetic recording medium efficiently with the deterioration or the like of divided recording elements being prevented positively. The production device (40) for a magnetic recording medium comprises a recording layer processing means (42) for dividing a continuous recording layer into many divided recording elements by forming at plane-direction fine intervals many grooves in the intermediate element (10) of a magnetic recording medium formed with the continuous recording layer, a non-magnetic element filling means (48) for filling a non-magnetic element into grooves between divided recording elements, a flattening means (50) for flattening the surfaces of divided recording elements and a non-magnetic element, a protection layer forming means (52) for forming protection layers on divided recording elements and a non-magnetic element, and a vacuum retaining means (56) for housing the recording layer processing means (42), the non-magnetic element filling means (48), the flattening means (50) and the protection layer forming means (52) to retain the surrounding of the intermediate element (10) in a vacuum condition.
