PROBLEM TO BE SOLVED: To provide a magnetic recording medium which has a high S/N (signal to noise ratio) and narrow effective write core width as compared with conventional one and whose recording density can be further enhanced, to provide a manufacturing method of the magnetic recording medium and to provide a magnetic recording device using the magnetic recording medium. SOLUTION: A backing layer 2, an FeCoB seed layer 3, a crystal orientation control layer 4 having an fcc structure, a non-magnetic underlayer 5, a first recording layer 6, a second recording layer 7 and a protective layer 8 are formed on a substrate 1. The backing layer 2 is constituted of three layers of a first soft magnetic layer 2a, a non-magnetic parting layer 2b and a second soft magnetic layer 2c. The first recording layer 6 has a granular structure wherein magnetic particles 6b are dispersed in a non-magnetic body 6a and the second recording layer 7 has a non-granular structure.
