    A dustproof case (20) containing a tape (23) with on one side a structure carrying optically readable information. The tape (23) is accomodated on two reels (21,22). The case (20) is provided with one window (25) through which a part of the tape (23) between the reels (21,22) is visible and with pressing means (24) for urging that part of the tape against the window (25). This pressing means (24) may be a wheel and the window (25) may have the shape of a cylindrical lens.

    2, the cassette according to claim 1, differs from the fact that elements with different optical properties are made in the form of projections with a reflecting surface on the side opposite to the pressure element, and the difference in the heights of the projections is equal to a quarter of the wavelength of light in air.
    3. The cassette pop. 1, is distinguished by the fact that elements with different optical properties have
    the protrusions located on the tape base from the side of the clamping element, made with a reflective surface, the ribbon base is made transparent, and the height of the protrusions is equal to a quarter of the wavelength of light in air.
    4, the cassette according to claim 3, so that the protrusions are made with a reflective surface from the side of the tape base.
    one
    The invention relates to the field of information storage, namely, cassettes with optical recording media.
    The purpose of the invention is to prevent damage to the optical recording media.
    FIG. 1 shows one of the possible variants of the proposed cassette with optical recording media; in fig. 2 and 3 embodiments of elements with different optical properties.
    The cassette contains a casing 1, in which the clamping element 2, made in the form of a cylindrical roller. The clamping element 2 is located against the window of the side wall of the casing 1 between the coils 3 and is coupled with an optical recording medium tape 4, made in the form of a tape base 5 and elements arranged on it with different optical properties. The side wall window 1 is made in the form of a cylindrical optical meniscus 6 coupled with an optical recording tape medium 4. The length of the cylindrical optical meniscus along its generatrix is equal to the width of the tape carrier 4 of the optical recording, and the casing 1 is filled with dust-proof.
    Elements with different optical properties can be made in the form of protrusions 7, having a reflective surface 8 and located on a tape base 5 from the side opposite to the clamping element 2
    (Fig. 2) .. In this case, the difference in the heights of the protrusions 7 is equal to a quarter of the wavelength of light in air.
    Elements with different optical properties may also have protrusions 9 located on the tape base 5 from the side of the clamping element 2, made with the reflecting surface 10 (FIG. 3). Moreover, the ribbon base 5 is made transparent, and the height of the protrusions 9 is equal to a quarter of the wavelength of the light at elevation. In this case, the protrusions 9 can be made with a reflective surface from the side of the tape base 5.
    The operation of the proposed tape with optical recording media is as follows.
    The light enters the housing 1 through
    a cylindrical optical meniscus 6, to which the optical recording medium 4 is pressed by the pressing member 2. In this case, the optical recording medium 4 is moved from
    relatively cylindrical optical meniscus 6 by rewinding it from one coil 3 to another.
    In the embodiment, from (& brazhenny figure 2, the light entering the casing 1 through
    the cylindrical optical meniscus 6 is reflected back from the reflecting surface 8. The difference in the distance traveled by the light rays reflected from the reflecting surface 8 of the protrusions 7 and the intervals between them is half the length of the wave in the air.
    In the embodiment shown in FIG. 3, Vet entering the casing 1 through Chi31181569 4
    and from the surface of the protrusions 9 facing the tape-shaped 5. Herewith 5 Using the invention, the difference in distance traveled is prevented by preventing the damage by the tape rays reflected from the reflected optical recording medium.
