  Recording mechanisms and characteristics have been investigated by computer simulation on an obliquely oriented medium whose easy magnetization direction is in the neither perpendicular nor longitudinal direction. It has been shown that the magnetization direction in the inside of the medium is fixed by the leading head field but the magnetization transition is formed around the trailing edge. The demagnetizing field in the obliquely oriented medium is weak not only at a low density but also at a high density, because the anti-parallel magnetization mode is formed. Besides, the distribution of the oblique component of a ring head field is sharper than those of the longitudinal and perpendicular components. Therefore the much better recording performances are obtained comparison with longitudinal magnetic recording.
