Magnetic recording medium and magnetic storage apparatus

A magnetic storage apparatus comprising:

• a magnetic recording medium;
• and
• a head configured to write information on and read information from the magnetic recording medium,
• wherein the magnetic recording medium includes
• a substrate;
• a magnetic layer including an alloy having an L10 type crystal structure as a main component thereof;
• a plurality of underlayers arranged between the substrate and the magnetic layer;
• and
• a barrier layer made of a material having an NaCl structure,
• wherein the plurality of underlayers include at least one crystalline underlayer including Mo as a main component thereof, and at least one of Si and C in a range of 1 mol % to 20 mol % and an oxide in a range of 1 vol % to 50 vol %, and
• wherein the barrier layer is provided between the magnetic layer and the at least one crystalline underlayer including Mo.
