A magnetic recording medium having a substrate, a first magnetic layer and
a second magnetic layer, in this order, wherein an exchange coupling in
the first magnetic layer is lower than an exchange coupling in the second
magnetic layer, and the first and second magnetic layers are in a film
stack so that magnetic grains in the first magnetic layer are exchange
coupled by a pathway through the second magnetic layer is disclosed. A
method of manufacturing a magnetic recording medium by obtaining a
substrate, depositing a first magnetic layer at a first sputter gas
pressure and depositing a second magnetic layer at a second sputter gas
pressure, in this order, wherein the first sputter gas pressure is higher
than the second sputter gas pressure, and an exchange coupling in the
first magnetic layer is lower than an exchange coupling in the second
magnetic layer is also disclosed.
