Description

【００２８】
また、この磁気記録媒体は、非磁性支持体の強磁性金属薄膜が成膜される主面に、高さ５〜５０ｎｍの微細突起が、１×１０２〜１×１０４万個／ｍｍ２の範囲内で形成され、微細突起側から求めた負荷曲線の上部２５％において、微細突起の個数が１０２〜５×１０２万個／ｍｍ2の範囲とされ、各微細突起の断面積の総和の割合が０．１〜０．５％の範囲とされていることが望ましい。[0028]
Furthermore, in this magnetic recording medium, it is desirable that fine protrusions 5 to 50 nm in height are formed in a range of 1 x 102 to 1 x 104,000 pieces/ mm2 on the main surface of the non-magnetic support on which the ferromagnetic metal thin film is formed, the number of fine protrusions in the upper 25% of the load curve obtained from the fine protrusion side is in the range of 102 to 5 x 102,000 pieces/ mm2 , and the proportion of the total cross-sectional area of each fine protrusion is in the range of 0.1 to 0.5%.
