Abstract

Описан носитель (1) записи, который имеет серводорожку (4), указывающую на информационную дорожку (9), предназначенную для записи информационных блоков, при этом серводорожка (4) имеет изменение физического параметра, так называемую вобуляцию. Вобуляцию модулируют для кодирования информации носителя записи, такой как адреса. Серводорожку подразделяют на модулированные участки, на которых частота и/или фаза изменения отклоняется от частоты вобуляции, и немодулированные участки. При использовании вобуляции (25, 26, 27, 28) угловой коэффициент вобуляции является, по существу, непрерывным на переходах между модулированными и немодулированными участками, начинающимися в максимумах или минимумах вобуляции на первом участке из модулированных участков.Международная заявка была опубликована вместе с отчетом о международном поиске.
