    Abstract: The invention relates to a permanent memory structure supported by a moving substrate.This substrate is formed by two metal layers (9, 10) vacuum-deposited on the relatively inexpansible substrate (1). One of the two metal layers is very expansible (9), while the other layer (10) is relatively inexpansible, but ductile. During inscription by the laser beam, the beam energy absorbed by the layers (9, 10) produces an elongation of the expansible layer (9), which deforms the ductile layer (10) by stretching it beyond the elastic limit. There is a permanent deformation of the two-layer assembly, without perforation.Particular application to optical disks.

    Abstract: The invention relates to a reversible memory structure with thermo-optical inscription or writing and optical reading on a moving support.According to the invention, the memory structure deposited on a substrate (1) is constituted by a double layer (2 and 3). A second alloy layer (3) at ambient temperature in the martensitic phase is deposited on a first thermally deformable layer (2). A heat pulse creates a deformation in the first layer, which deforms the martensitic alloy layer. A more powerful heat pulse raises the alloy layer to a temperature above its transformation point from the martensitic phase to another crystallographic phase and erases the inscribed deformation.Particular application to optical disks.

    Abstract: The invention relates to protected optical disk structures. The invention relates placing the sensitive layer on a substrate, which is only joined to the other elements constituting the box by a single fixing area, located in the central part of said box, in order that deformations of the box do not affect the smoothness and flatness of the substrate.

    Abstract: A protected optical disc intended for the recording of information is protected against the harmful consequences of humidity by the presence of a hydrophylous material situated at a particular distance from the recording surface, which thus retains a high sensitivity during the write or read operations. The invention may be applied especially to discs intended for digital recording.
