Abstract
UN CONTADOR PARA CONTAR MARCAS, EJ., PISTAS DE DATOS EN UN SOPORTE DE GRABACION. LOS IMPULSOS CONTADORES SON ENVIADOS A UN CONTADOR PROGRESIVO-REGRESIVO PARA CONTAR LAS MARCAS SOBRE LAS QUE PASA UN ESCANER, EJ. LAS PISTAS DE DATOS DE UN DISPOSITIVO DE GRABACION OPTICO EXPLORADO POR UN HAZ LUMINOSO. DEPENDIENDO DE LA DIRECCION EN QUE SE MUEVE EL ESCANER, UN CIRCUITO LOGICO DIRECCIONAL DETERMINA LA DIRECCION DE CONTEO DEL CONTADOR PROGRESIVO-REGRESIVO. PARA EVITAR ERRORES DURANTE EL CONTEO DE LAS PISTAS, SE DEBE PRESTAR ATENCION A LA RELACION DE FASE DE LOS IMPULSOS DE CONTEO Y LA SEÑAL DE SALIDA DEL CIRCUITO LOGICO DIRECCIONAL. PARA PODER CONTAR EL NUMERO DE MARCAS O PISTAS EXPLORADAS INDEPENDIENTEMENTE DE LA RELACION DE FASE DE LOS IMPULSOS DE CONTEO Y LA SEÑAL DE SALIDA DEL CIRCUITO LOGICO DIRECCIONAL (RL), LOS IMPULSOS DE CONTEO (ZI) SON LLEVADOS A UN PRIMER CONTADOR (Z1) CUANDO EL ESCANER O EL HAZ LUMINOSO CRUZA LAS MARCAS O PISTAS EN LA DIRECCION DESEADA; SIN EMBARGO, LOS IMPULSOS DE CONTEO (ZI) SON APLICADOS A LA ENTRADA CONTADORA (V) DE UN SEGUNDO CONTADOR (Z2) CUANDO EL ESCANER CRUZA LAS MARCAS EN UNA DIRECCION NO DESEADA. PARA SALTAR M MARCAS, EL PRIMER CONTADOR (Z1) SE CONFIGURA A UN PRIMER VALOR PREDETERMINADO MIENTRAS SE QUE SEGUNDO (Z2) SE CONFIGURA A UN SEGUNDO VALOR PREDETERMINADO. CUANDO LAS LECTURAS DEL CONTADOR COINCIDEN, EL ESCANER O EL HAZ LUMINOSO SE PARAN. DISPOSITIVOS CONTADORES PARA CONTAR LAS MARCAS O PISTAS DE DATOS QUE SON EXPLORADAS MECANICAMENTE O SIN CONTACTO, EJ. EN TOCADISCOS DE CD, REPRODUCTORES DE CINTAS DE VIDEO, TOCADISCOS DE DISCOS DRAW O DISPOSITIVOS DE GRABACION Y/O REPRODUCCION MAGNETOOPTICOS.
