PURPOSE:To use a magnetic recoring body at a high speed of 2-10m/sec while improviding durability, the dropout of a lubricant layer, the possibility of the generation of wrinkles, etc., by improving the lubricant layer. CONSTITUTION:On both surfaces of a base 2 provided with a magnetic layer 1 on the top surface, a lubricant layer 3 which consists essentially of a lubricant, such as graphite, and a bonding component and has 2.5-5mum thickness and 0.33-0.72mum surface characteristic (Ra value) is provided. |
