Abstract
A disc cartridge capable of enhancing operability of both a cover and an erasure preventing plug while ensuring smooth removal of a disc shaped medium therefrom. An upper casing member and a lower casing member are formed with cutouts, respectively, and the cover is provided with projections fitted in the cutouts of the upper casing member and lower casing member, respectively. The cutouts of the upper casing member and lower casing member and the projections of the cover cooperate with each other to provide an operation hole for the erasure preventing plug and a detection hole therefor, respectively.
