An optical recording element capable of recording and retrieving information by means of beam radiation, comprising a recording layer vacuum deposited onto a protective layer, and an adhesive layer which securely adheres said recording layer to a substrate. The protective layer is prepared from a light-transmitting sheet or plate, with no adhesive layer intervening between the protective layer and the recording layer, so that the influence of dust and bubbles in recording and retrieval can be minimized.
