A recording medium cartridge housing a disc wherein the vibration of the disc can be reduced by printing a vibration isolating ink layer containing acrylic particles and having a projecting and depressing surface on a portion including at least a support area of an upper half of the cartridge housing. The isolating ink layer acts by absorbing the vibration transmitted to the cartridge housing.
