To obtain the function for cleaning a magnetic head by providing protrusions on a magnetic recording medium having a magnetic recording layer so as to contact with the magnetic head which is brought into contact with the magnetic recording layer for the magnetic recording operation.

The protrusions 4 are provided on the magnetic recording medium 2 so as to contact with the magnetic head. The protrusions 4 are allowed to arrange on the places such as the parts up to the right before a first frame (tip parts) of photographic picture frames 5 on the magnetic recording medium 2, the remaining parts from the right after a last frame (rear end parts) of the photographic picture frames 5, or the parts where the magnetic information is not inputted/outputted from the first frame to the last frame (e.g. parts around the perforations or the parts between the frames). These protrusions are provided in the quantity of ≥0.5 piece/mm and ≤10 pieces/mm in the running direction of magnetic recording medium 2.
