Abstract

PURPOSE:To obtain a magnetized recording medium that is capable of the accurate and high-speed reading with high density, by providing a horizontal magnetized recording film on the opposite surface of a base having the horizontal and vertical magnetized films. CONSTITUTION:Both a horizontal magnetized film 12 and a vertical magnetized film 13 are formed on the upper surface of a base film 11 in addition to an ordinary vertical magnetized recording medium. At the same time, a horizontal magnetized recording film 14 composed of a ferromagnetic material thin film that extracts accurately the position signal recorded on the film 12 is provided on the opposite surface of the film 11.
