Structure of memory reversible, has an optical thermoplastic - writing and optical reading, and of writing and erasure of this structure

摘要

P the invention relates to a structure of a write memory reversible heat - optical and optical reading, on a support scrolling. / p & & p & according to the invention, the structure of memory, filed on a substrate 1, is constituted by a double layer 23 on a first layer 2 is thermally deformable filed a second layer 3 of an alloy which is located at the ambient temperature in the martensitic phase. A thermal pulse creates a deformation in the first layer, which deformed the layer of martensitic alloy. A thermal pulse more powerful bring the layer of alloy has a temperature which is greater at the temperature of transition of the martensitic phase to a crystallographic phase, and the deformation which is inscribed. / p & & p & application in particular to the optical disks. / p
