PROBLEM TO BE SOLVED: To provide a magnetic tape which is adaptable for the characteristics of a magnetoresistance head and which shows good electromagnetic conversion characteristics, and especially to provide a magnetic tape suitable to be used as a magnetic recording reproducing system assembled with a MR magnetic head which enables recording at a high data transfer rate and high density. SOLUTION: This magnetic tape has a nonmagnetic layer which contains a nonmagnetic powder and a binder and which is substantially nonmagnetic, and a magnetic layer containing a ferromagnetic powder and a binder formed in this order on one surface of a supporting body and has a back coating layer containing carbon black formed on the other surface of the supporting body. The thickness of the magnetic layer ranges from 0.08 to 0.28μm, and the magnetic flux of the magnetic layer ranges from 0.02 to 0.1 G.cm. |
