Abstract

Un medio de registro optico para derivar en forma segura la informacion de direccion o la informacion de control de rotacion de disco a pesar de la inclinacion de pista angosta, y para registrar señales a una densidad elevada, y un método y un aparato para registrar y/o reproducir dicho medio de registro optico. El medio de registro optico tiene una ranura balanceada y agujeros formados en un intervalo preajustado en un área entre espiras de la ranura balanceada. El método de registro/reproduccion incluye controlar la rotacion del medio de registrooptico mediante una señal balanceada de la ranura y detectar la posicion en el medio de registro optico de una señal de registro mediante señales de perforacion detectadas por los agujeros. El aparato de registro/reproduccion incluye un dispositivo de deteccion para detectar la señal balanceada de la ranura y un dispositivo de deteccion para detectar las señales de perforacion de los agujeros. La rotacion del medio de registro optico se controla mediante las señales equilibradas detectadas de la ranura y la posicion en el medio de registro optico de la señal de registro se detecta mediante la señal de perforacion detectada de los agujeros.
