description PROBLEM TO BE SOLVED: To provide a magnetic recording medium excellent in shelf stability and nearly free from a dropout after long-term storage. SOLUTION: The magnetic recording medium is obtained by providing a base coated layer on a non-magnetic substrate and at least a magnetic recording layer formed by coating on the base coated layer. Polyester resin manufactured from a raw material containing naphthalene dicarboxylic acid as a dicarboxylic acid component is used for the base-coated layer, and the glass transition temperature of the overall base-coated layer is
