ABSTRACT:
A magnetic tape cartridge incorporating a drive belt characterized by a smooth (e.g., average surface roughness less than 7 microinches, zero to peak, as measured by a Talysurf 10 surface analyzer set for a 0.003 cut off length) nontextured drive surface and a ratio of static to dynamic coefficients of friction between the drive surface and the magnetic tape surface, of less than 2. The drive belt is preferably integrally formed of a material which inherently yields the aforementioned drive surface characteristics without requiring that the naturally formed belt surface be specially treated.
