    Abstract: A magnetic tape cartridge and its recorder/reproducer in which a magnetic head can be protected against damage by suppressing charging of a magnetic tape while lowering the resistance thereof and sustaining high electromagnetic conversion characteristics. A tape reel (7) is formed of a conductive material and the surface resistivity “Ω/sq” at one end part of a magnetic tape (6) being connected to its reel hub (7B) is set not higher than 10 7 . Since the magnetic tape (6) has a multilayer structure of a magnetic layer (23), a nonmagnetic conductor layer (22), a plastic film (21) and a back coat layer (24) formed from the magnetic face (6M) side, the exposed nonmagnetic conductor layer (22) is connected to a reel hub (7A) even when the surface resistivity of the magnetic layer (23) exceeds 10 7 Ω/sq by removing the magnetic layer (23). Consequently, the resistance of the magnetic tape is lowered while sustaining high electromagnetic conversion characteristics.
