| titleOfInvention | Magnetic recording medium |
| abstract | A magnetic recording medium comprises a substrate composed of a polyimide film bearing, on a face thereof, a polyimide coated layer containing inorganic particles dispersed therein, and a magnetic recording layer formed on said polyimide coated layer. n A magnetic recording medium comprises a substrate composed of a polyimide film containing inorganic particles dispersed therein and bearing, on a face thereof, a polyimide coated layer containing inorganic particles dispersed therein, and a magnetic recording layer formed on the other face of said polyimide film, wherein the average particle size of the inorganic particles dispersed in said polyimide film is smaller than that of the inorganic particles dispersed in said polyimide coated layer. n A magnetic recording medium comprises a magnetic recording layer formed by a thin film deposition process on a substrate, wherein said substrate is provided, on the surface thereof, with small projections with a density of 10⁵ to 10⁸ projections/mm², and the statistical distribution of the heights of said projections satisfies following relations H 0.01 < 600 Å, H 0.1 > 120 Å, H₁ > 100 Å and H 0.1 200 Å, in which H 0.01 , H 0.1 and H₁ are the heights of projections respectively corresponding to 0.01 %, 0.1 % and 1 % of the total number of projections in the descending order of height. n A magnetic recording medium comprises a magnetic recording layer formed by a thin film deposition process on a substrate containing inorganic particles dispersed therein, wherein said substrate is provided, on the surface thereof, with small projections with a density of 10⁵ to 10⁸ projections/mm², wherein said inorganic particles are mostly dispersed to the level of primary particles, and wherein the distribution of the heights of projections on the surface of the substrate satisfies following relations: nH 0.01 < (1 + σ)d nH 0.1 >120 Å nH₁ > 0.35d nin which d is the average particle size of the inorganic particles; σ is the deviation in said particle size; and H 0.01 , H 0.1 and H₁ are the heights of projections respectively corresponding to 0.01 %, 0.1 % and 1 % of the total number of projections in the descending order of height. |
