Abstract

PURPOSE:To achieve transfer for high-density recording, by using a master composed of CoCr of vertical magnetic anisotropy, and bringing it contact with slave for heating. CONSTITUTION:A CoCr film 18 is used as a magnetic substance layer for a master medium 20, a TbFe film is used as a magnetic substance film 15 as a slave medium 17, a protective film made of SiO2 is attached on it, these planes are closely adhered mutually, thermal light rays from a high-brightness light source such as halogen lamp are irradiated, and the signals written on the master medium 20 are transferred to the slave medium 17 by heating the adhered planes at the Curie temperature or more of the film 15 and at the Curie temperature or less of the film 18. High-density transfer can be made without an unclear magnetizing transition point due to the effect of a demagnetizing field, by using a material with excellent vertical magnetic anisotropy both for master and slave media.
