Magnetic recording medium, magnetic storage apparatus and recording method

摘要

A magnetic recording medium is provided with a first magnetic layer (26), a nonmagnetic coupling layer (28) provided on the first magnetic layer (26), and a second magnetic layer (29) provided on the nonmagnetic coupling layer (28). The first and second magnetic layers (26 & 29) are exchange-coupled, and have magnetization directions which are mutually parallel in a state where no external magnetic field is applied thereto, and the first magnetic layer (26) switches the magnetization direction thereof before the second magnetic layer (29) in response to a recording magnetic field which switches the magnetization directions of the first and second magnetic layers (26 & 29).
