Abstract

Дискообразный накопитель двоичной информации, которая последовательно записана вдоль спиральной дорожки в виде питов и лэндов, считываемых лазерным лучом по интерференционному принципу, можно маркировать так, что его нельзя будет спутать с подделкой и подделать за счет того, что выбранное число лэндов выполняют в оптической базисной поверхности в виде углублений, плоских по сравнению с глубиной питов. Эта маркировка, в принципе, любой формы может быть настолько маленькой, что ее можно обнаружить только электронным микроскопом, а также такой большой, что ее можно увидеть простым глазом при смешанном свете.

  1. Дискообразный накопитель двоичной информации, которая последовательно записана вдоль спиральной дорожки в виде питов и лэндов, считываемых лазерным лучом по интерференционному принципу, можно маркировать так, что его нельзя будет спутать с подделкой и подделать за счет того, что выбранное число лэндов выполняют в оптической базисной поверхности в виде углублений, плоских по сравнению с глубиной питов. Эта маркировка, в принципе, любой формы может быть настолько маленькой, что ее можно обнаружить только электронным микроскопом, а также такой большой, что ее можно увидеть простым глазом при смешанном свете.
