Title: Medium for magneto-optical memory
Inventor: KOBAYASHI TADASHI
IPC: G11B11/10
Filed: 1986-07-09
Abstract: PURPOSE:To improve corrosion resistance and exchange bond by using Tb-Fe for a recording layer and Gd-Fe-Co for reading out layers and sandwiching the recording layer with the reading out layers. CONSTITUTION:This medium is formed by having the recording layer having the three-layered structure making the exchange bond by sandwiching the recording layer having high coercive force at a room temp. and low Curie temp. with the reading out layers having low coercive force and high Curie temp. The recording layer consists of Tb-Fe and the reading out layers consist of Gd-Fe-Co. The corrosion from the boundary face between the magnetic layer and protective layer is prevented by sandwiching the recording layer consisting of the Tb-Fe with the Gd-Fe-Co of the reading out layers having the good corrosion resistance.
