Abstract
An endless tape cartridge, preferably for use with magnetic recording-reproducing apparatuses, comprises a plurality of loose rollers opposed to one end face of an endless tape coil in the cartridge and disposed radially of the tape coil. Within the cartridge, brake means having its end face for uniform resilient engagement with the end face of the tape coil is cockably or pivotally mounted. The brake means is arranged so that its resilient pressure force imparted to the coil end face may be released from outside the cartridge through openings formed in the cartridge wall.
