| 摘要 |
The present invention provides a magnetic recording medium having a magnetic layer formed on at least one surface of a nonmagnetic support, wherein the magnetic layer includes a ferrite ferromagnetic hexagonal powder having an average plate diameter of 5 to 50 nm or a fine ferromagnetic metal powder having an average major axis length of 20 to 100 nm together with a binder, and the nonmagnetic support is a composition of a polyester or copolyester having one or more of polytrimethylene 2,6-naphthalate, polytetramethylene 2,6-naphthalate, polypentamethylene 2,6-naphthalate and polyhexamethylene 2,6-naphthalate, in order to provides an excellent running stability, low error rates under various environment and an excellent electromagnetic transforming properties and reliability.
