Provided is a cartridge capable of curbing charging of a magnetic tape even in a case where a drive gear is configured of an insulating resin. The cartridge includes a reel that has conductivity and includes a bottom wall, a magnetic tape that is wound around the reel, and a conductive member that is in contact with the reel, the conductive member having a reel gear on a lower surface of the bottom wall.

Cartridge including magnetic tape including magnetic layer including protrusions on surface thereof

A tape reel according to an embodiment of the present technology includes: a cylindrical reel hub that includes an outer periphery portion, a tape being wound on the reel hub. The reel hub is formed of a material in which a deformation amount when a load of 300 N is applied radially inward to an axial center of the outer periphery portion is 0.3 mm or less and a water absorption rate is 0.1% or less.
