Claim:
A magnetic recording and reproducing apparatus, comprising: a magnetic recording medium of a perpendicular recording type, the magnetic recording medium including a track pattern having track portions and gap portions arranged so as to be alternately adjacent to each other in a cross-track direction, at least part of portions corresponding to the track portions being recording areas having a width substantially the same as a width of the track portions, portions between the recording areas being non-recording areas; and a magnetic head of a perpendicular recording type for applying a recording magnetic field to the recording areas, wherein an anisotropic magnetic field Hk (T) of the recording areas of the magnetic recording medium and a recording magnetic field intensity Fw (T) of the recording magnetic field at an upper surface of the recording areas satisfy the following inequality (I): 0.23 Ã—Fw+ 1.2 â‰¦Hkâ‰¦ 0.26 Ã—Fw+ 1.6.â€ƒâ€ƒ(I)
