Abstract

A tape cartridge and reel for storing magnetic tape wound on the reel such that damage to the edges of the magnetic tape is significantly reduced. A protective ring is formed in the reel or in the tape cartridge such that shock-induced energy is transmitted through a defined path. Transmission of the shock-induced energy through the defined path is effective to avoid the compression of the flanges of the reel so that the edges of the magnetic tape are not folded, wrinkled, or otherwise damaged.
