PROBLEM TO BE SOLVED: To provide a magnetic recording medium capable of suppressing off-track. A magnetic recording medium (10) is a tape-shaped magnetic recording medium, and includes a base (11) and a magnetic layer (13) provided on the base. The magnetic layer is configured to be capable of forming a plurality of data tracks, the width of the data tracks is 2900 nm or less, and the temperature and relative humidity are (10 ° C., 10%), (10 ° C., 80%), (29 ° C.). , 80%) and (45 ° C., 10%), where w max and w min are the maximum and minimum values of the average width of the magnetic recording medium measured under four environments, respectively. max and w min satisfy the relationship of (w max −w min ) / w min ≦ 400 [ppm].
