Abstract: Using corner roller assemblies with different drag force profiles provides improved control in establishing tape tension characteristics of a belt-driven tape cartridge. The belt-driven tape cartridge has a tape tension profile and is of the type comprising first and second corner roller assemblies defining a portion of a drive-belt path of a cartridge. The first corner roller assembly has a first drag force profile and includes a first shaft and a first rotating member comprising a first bore. The first rotating member is rotatably mounted on the first shaft, such that the first shaft is disposed in the first bore. The second corner roller assembly has a second drag force profile and includes a second shaft and a second rotating member comprising a second bore. The second rotating member is rotatably mounted on the second shaft, such that the second shaft is disposed in the second bore. The first and second corner roller assemblies are configured such that the drag force profile of the first corner roller assembly is preselected to be different from the drag force profile of the second corner roller assembly in order to totally establish the tape tension of the cartridge.
