Abstract

Съгласно методите в апарата за оптичен запис се установява оптималната мощност за запис на снопа лъчение чрез записване на поредици от тестови структури върху среда за оптичен запис. Следва формиранена прочетени сигнали от структурите и обработване на прочетения сигнал. Обработването включва избор на функция, за предпочитане права линия съгласно параметрите, получени от прочетения сигнал, без използване на операцията диференциране.
