A discrete track-type magnetic recording medium (30) includes a nonmagnetic substrate (1), a magnetic recording track and a servo signal pattern which are provided on at least one side of the nonmagnetic substrate, and a nonmagnetic part (4) consisting of a nonmagnetic alloy containing Si for physically separating the magnetic recording track and the servo signal pattern. A magnetic recording and reproducing device comprising, in combination, the magnetic recording medium (30), a driving part (26) serving to drive the magnetic recording medium in a direction of recording, a magnetic head (27) composed of a recording part and a reproducing part, a device (28) to impart motion to the magnetic head relative to the magnetic recording medium, and a recording and reproducing signal processing device (29) for entering a signal into the magnetic head and reproducing an output signal from the magnetic head.
