    All are made of metal and plastic.

    The plastic: because they need to be transparent on one side (or both, depending on the disc type) so that the player can read the data contained inside the disc.

    The metal: for a DVD is typically aluminum AND gold.

    CDs were aluminum, and when they first became popular some companies were selling special, high-end gold instead of aluminum, claiming some advantage or other. I don't think it sold well, considering that the regular (aluminum) CD produced equally good sound quality.

    It is impractical to make them with pure metal, because all of them already contain a very thin layer of aluminum under the protected plastic coating.

    They used gold to make special one, don't know about aluminum and steel. DVD are already history.
