Abstract
A disk cartridge has a projection on an inner surface thereof. The projection is located proximate the head access opening to prevent medium distortion during cartridge insertion. The cartridge is designed for insertion into a drive in which the medium is mounted by translating the medium within the cartridge away from a spindle access opening in the cartridge. The translation of the medium can cause the medium to twist thereby distorting the peripheral edge of the medium. The projection on the inner surface of the cartridge inhibits the medium distortion.
