Abstract

PURPOSE:To enable non-contact detection by visualizing the magnetized pattern of a magnetic recording medium where digital data consisting of a binary code is magnetically recorded, by a magnetized pattern sensor and reading it optically by using an image sensor. CONSTITUTION:A magnetically recorded digital data reader 11 visualizes the magnetized pattern of a magnetic tape 8 where the digital data consisting of the binary code is magnetically recorded by the magnetized pattern sensor 12 and the visualized magnetized pattern is read optically by the image sensor 13. By this constitution, the non-contact detection is possible without bringing the magnetized pattern sensor 12 into contact with the magnetic tape 8 and the durability of both the magnetic tape 8 and the magnetized pattern sensor 12 is raised.
