Abstract
Elastic lifters arranged on an inner surface of a casing of a disc cartridge to act pressing force on a disc each are formed integral with the casing and into a plate-like shape in such a manner that a proximal end thereof is mounted on the casing and the a end thereof is rendered free. Such construction permits the pressing force to be kept constant for a long period of time and effectively prevents damage to the disc-like medium, to thereby substantially improve durability and reliability of the disc cartridge while significantly decreasing the number of parts, facilitating assembling of the disc cartridge and attains a decrease in manufacturing cost.
