| titleOfInvention | Magnetic tape cassette |
| abstract | A 2 reel type data storage magnetic tape cassette ( 20 ) is provided with reels ( 28, 30 ) around which a magnetic recording medium ( 26 ) is wound. The magnetic recording medium ( 26 ) includes a support, a non-magnetic layer comprising a non-magnetic powder and a binder on one surface of the support, a magnetic layer comprising a ferromagnetic metal powder and a binder on top of the non-magnetic layer, and a back layer comprising a carbon black powder and a binder on the other side of the support. The magnetic tape cassette ( 20 ) is further provided with a rotating guide roller ( 36 ) made of a resin within the cassette ( 20 ). The rotating guide roller ( 36 ) has a ten-point average roughness Rz of 3.0 to 4.5 μm and is in contact with the surface of the magnetic layer having a center plane average roughness SRa of 2.0 to 3.5 nm. |
