Magnetic recording medium, magnetic recording/reproducing apparatus, and stamper for manufacturing the magnetic recording medium

A magnetic recording medium comprising a recording layer divided into a plurality of data areas and a plurality of servo areas to record information, wherein

• each of the servo areas has a burst signal region for detecting a position of a magnetic head at each track in the data areas,
• the burst signal region is provided with burst signal groups each of which is longer in a length-wise direction of the track than in a width direction of the track,
• the recording layer is formed in a concavo-convex shape in a predetermined servo pattern in each of the servo areas, with servo signal unit portions formed as either convex portions or concave portions of the concavo-convex shape,
• a plurality of burst signal unit portions of the servo signal unit portions are arranged side by side in a row in the length-wise direction of the track in each of the burst signal groups,
• at least the burst signal unit portions of the servo signal unit portions are generally elliptical in shape when viewed from a direction of thickness, and
• the burst signal unit portions are configured such that 0.5≦Rt/Rs<1 is satisfied, where Rt is a width in the width direction of the track, and Rs is a width in the length-wise direction of the track.
