Magnetic recording medium.

摘要

A magnetic recording medium having an improved output property over the wide range of wavelength, by controlling the magnetic reluctance and saturated magnetic flux density of the outermost layer and at least one layer other than the outermost layer, as specified in the claims, is disclosed. A magnetic matal powder contained in the outermost layer has an average major axis length of not more than 250 nm and a ratio of the average major axis length divided by an average X-ray measured particle size is less than 12.
