    An interchangeable optically readable storage disk has a substrate with a recording surface, and a cover thereon which may comprise a second substrate with a further recording layer. The disk includes a protecting arrangement at the circumference of the substrate, which includes a balancing arrangement. The balancing may be effected by apertures in the protecting arrangement, or balancing masses affixed thereto.

    The invention relates to computing technology and can be used in the construction of optical storage devices.
      The aim of the invention is to increase the reliability of an optical disk storage device.
    FIG. Figures 1-6 illustrate optical disk storage (memory disk) options.
    The optical disk storage device (Fig. 1) contains a transparent substrate 1 on which a sensitive recording layer 2 is applied which can be changed under the Radiation Effect. The disk-shaped cover 3 is attached to the substrate 1 at some distance from the layer 2 by means of damping elements in the form of rings 4 and 5, so that the cavity 6 is closed between the substrate and the cover. The cover 3 is identical to the substrate 1 and is also provided with a sensitive recording layer (not shown). In this way, a double-sided disk storage device is obtained, with one substrate forming a lid for the other substrate. Rings 4 and 5 are concentric annular struts. The annular spacer 4 includes a part 7, which extends beyond the circumference of the substrate and the cover 3 and serves as a balancing means for correcting the eccentric position of the center of mass of the memory disk. For this purpose, holes 8 can be made in the ring so that the material is removed locally. In many cases this is not enough, and mounting a balancing mass, such as lead, on the protruding part of the ring 4. This can be used holes 8.
    The memory disk (FIG. 2) is different from the memory disk shown in FIG. 1, by the fact that the profile of the ring of the damping element is T-shaped and is located perpendicular to the edge of the part of the ring at some distance from the substrate 1 and the cover 3. The balancing mass is located between the substrate and the inner surface of the end part of the ring of the damping element. The memory disk has a symmetrical design, and the balancing masses can be installed on both icTOpoH memory disks.

    Numerous modifications of the memory disk are possible. FIG. Figure 3 shows a memory disk in which the profile of the ring of the damping element is V-shaped, and the balancing mass is placed between the teeth of the ring of the damping element on its outer surface.
    FIG. Figure 4 shows a memory disk in which the mat is made of a thin aluminum sheet or other material and is attached to the substrate with an adhesive means, the outer diameter of the cover being larger than the diameter of the substrate.
    Figures 5 and 6 show other mounting options for the lid with the substrate and various mounting options for the balancing mass.
