Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a magnetic recording medium which obviates film bulging even under severe conditions. SOLUTION: This magnetic recording medium is formed by successively laminating at least a nonmagnetic ground surface layer, magnetic layer, protective film and liquid lubricant layer on a nonmagnetic substrate, in which the nonmagnetic substrate is plastic and a groove along a circle having nearly the same center as an outer periphery is formed in a range of
