Abstract

Описан носитель записи (1), имеющий серво-дорожку (4), указывающую на информационную дорожку (9), предназначенную для записи информационных блоков. В серво-дорожке (4) обеспечено периодическое изменение физического параметра с заранее определенной частотой, обычно называемое "вобуляцией". Серво-дорожка имеет модулированные части для кодирования информации о положении в соответствии с заранее определенным типом модуляции. Носитель записи содержит зону управления, где серво-дорожка содержит постоянные данные. Постоянные данные кодируют с использованием модуляции другого типа, но с использованием изменений того же физического параметра. В качестве модуляции другого типа предложена непосредственная цифровая модуляция (41). Кроме того, описано устройство для считывания и/или записи на носитель записи.Международная заявка была опубликована вместе с отчетом о международном поиске.
