Abstract

1.- Una portadora de grabación que comprende una servo pista (4) que indica una pista de información (9) con el propósito de grabar bloques de información, dicha servo pista (4) tiene una variación de un parámetro físico en una frecuencia predeterminada dicha variación está modulada para codificar información de portadora de grabación, ydicha servo pista tiene parte moduladas en las cuales la frecuencia y/o la fase de la variación se desvía de la frecuencia predeterminada, y partes no moduladas que tienen solamente dicha variación periódica, caracterizada en que la pendiente de la variación es sustancialmente continua en las transiciones entre las partes moduladas y las no moduladas.2.- La portadora de grabación según la reivindicación 1 en donde la variación es sustancialmente sinosoidal y las transiciones están localizadas en los mínimos y /o máximos de dicho seno.
