A recording and reproducing apparatus includes: a recording section for recording an information signal in a magnetic recording medium in which a magnetic layer containing hexagonal ferrite is formed; and a reproducing section for reproducing the information signal recorded in the magnetic recording medium, the reproducing section including: a reproducing head for reading the information signal from the magnetic recording medium; and an equalizer for equalizing the information signal read from the magnetic recording medium, wherein in the equalized information signal, coefficients a, b, c, d of PR(1, a, b, c, d) meet conditions that 0.1<=a<2.0, -0.9<=b<-0.0, -2.0<c<=-0.3, and -1.0<d<=-0.1. A corresponding reproducing method, a corresponding reproducing apparatus, and the magnetic recording medium are also disclosed.
