A data disc protector and a method for using same to protect data discs stored in data disc storage cases is disclosed. Embodiments of the data disc protector comprise a protective sheet of material sized to fit between a data disc and a back cover of a data disc storage case and adapted to form a barrier between the back cover and the data disc when sandwiched between a data disc and the back cover. The data disc protector forms a physical barrier inhibiting the transfer of airborne hydrocarbons emitted by plastics in the storage case to the disc and preventing the data disc from contacting the back cover during storage. Embodiments of the data disc protector are made of a material that traps hydrocarbons. Embodiments of the data disc protector are provided with a central aperture adapted to allow installation on a hub in the storage case.
