Beschreibung
Zusammenfassung:	A magnetic recording medium includes: a flexible and elongated substrate; a soft magnetic layer having an average thickness of 10 nm or more to 50 nm or less; and a recording layer, in which the soft magnetic layer is disposed between the substrate and the recording layer, and a difference in Young's modulus between the magnetic recording medium and the substrate in a longitudinal direction of the substrate is 2.4 GPa or more.
