Abstract

Настоящее изобретение относится к способу и устройству (100) определения параметра, предназначенным для определения значения первого параметра смещения фокуса. Способ определения этого значения параметра для записи данных контента на многослойный носитель (114) информации содержит этапы записи последовательностей тестовых данных с использованием различных оценок значений первого параметра смещения фокуса (этап 206), считывания этих последовательностей тестовых данных (этап 206), определения значения по меньшей мере одного показателя отклонения данных, соответствующего считанным последовательностям тестовых данных (этап 206), и определения значения первого параметра смещения фокуса в зависимости от определенных значений по меньшей мере одного показателя отклонения данных (этапы 210, 222), из условия, чтобы была минимизирована частота ошибочных блоков для считывания данных контента, записанных на многослойный носитель (114) информации при использовании определенного значения первого параметра смещения фокуса и считываемых с многослойного портативного носителя (114) информации при использовании определенного значения второго параметра смещения фокуса.
