Abstract
Винахід належить до засобів створення носіїв інформації та засобів їх запису/читання. Описаний носій запису (1) з доріжкою стеження (4), яка вказує інформаційну доріжку (9), призначену для записування інформаційних блоків, репрезентованих мітками з вираженою в канальних бітах довжиною, причому певний фізичний параметр згаданої доріжки стеження (4) зазнав періодичного змінювання. Згадана періодична зміна модулюється для кодування інформації, що стосується носія запису, такої як адреси. Згадане модулювання є двофазним, за якого біт даних інформації, що стосується носія запису, кодується першою наперед визначеною кількістю змін з першою фазою, за якою йде така сама кількість змін з другою фазою, протилежною до першої. Записувальний і/або відтворювальний пристрій має демодулятор для відновлювання бітів даних інформації, що стосується носія запису, з першої наперед визначеної кількості змін першої фази, за якою йде така сама кількість змін другої фази, протилежної до першої. Винахід дозволяє поліпшити характеристики надійності, швидкості та точності запису/читання інформації носіїв запису.
