Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a magnetic recording media having good scratch resistance.SOLUTION: The magnetic recording media comprises a substrate and a laminated film according to an embodiment, when a film thickness of the laminated film is h and an indentation elastic modulus of the laminated film is E, a flexural modulus Eof the substrate satisfies a relationship represented by the following formula (1). E≤(200E)/(6h)... (1)SELECTED DRAWING: Figure 1
