A magnetic tape cartridge having at least one tape pack contains liners which form guide channels for the outer turns of the pack and/or for magnetic tape being wound or unwound and also include resilient sections for locating the tape pack and/or the winding hub in the central plane of the cartridge. The magnetic tape cartridge of the invention can be used with particular advantage as a compact cassette beacause of its outstanding reliability in operation.
