Abstract

"DISPOSITIVO DE VARREDURA PARA VARREDURA DE REGISTROS DE DADOS SOBRE UMA PORTADORA DE REGISTRO MAGNéTICO DE DADOS, E, PORTADORA DE REGISTRO COM INFORMAçõES GRAVADAS MAGNETICAMENTE SOBRE A MESMA". Trata-se de um dispositivo de varredura para varredura de discos portadores de dados. Os discos incluem uma camada magnetizável para a qual e da qual são gravados e lidos dados mediante utilização de um transdutor magnético, tal como um transdutor tipo Giant Magneto-Resistive (GMR). O posicionamento do transdutor sobre uma pista de dados é obtido por rastreamento óptico utilizando uma estrutura de ressaltos/ranhuras, e o posicionamento do transdutor relativamente ao sistema de rastreamento óptico é realizado por meio de um feixe de referência transmitido através do disco.
