The present invention provides a magnetic recording medium comprising: a non-magnetic substrate; and one or more magnetic layers formed on the non-magnetic substrate, wherein the magnetic recording medium has a loss modulus at 0.5 Hz at a temperature of 130° C. of 0.18 to 0.39 GPa, in order to improve dimensional stability and running stability of a tape, particularly in a high-temperature environment, and thereby improve reliability in recording and reproduction of data, and to provide a method for manufacturing the same. Also, the magnetic recording medium of the present invention attains the object to solve the problem that tension for driving generates nonuniform elongation in the medium, resulting in reduction of running stability because of a thin magnetic recording medium which is reduced the total thickness to increase the capacity of the backup tape per reel by increasing a tape length and increase. |
