Title: Thermomagnetic recording medium
Inventor: YOROZU KATSUHIKO
IPC: G11B11/10
Filed: 1989-04-21
Abstract: PURPOSE:To widen the range of laser power threshold as possible used for recording and erasing by providing a specific auxiliary layer between a thermomagnetic recording layer and an auxiliary thermomagnetic recording layer. CONSTITUTION:The thermomagnetic disk consists of a protective layer, thermomagnetic recording layer, auxiliary thermomagnetic layer and protective layer successively formed on a transparent substrate. Another auxiliary layer is provided between the thermomagnetic recording layer and the auxiliary thermomagnetic recording layer. It is required that the diamagnetic- ferromagnetic phase transition point of the auxiliary layer is higher than room temp. but lower than the Curie point of the auxiliary thermomagnetic recording layer. If the antiferromagnetic-ferromagnetic phase transition temp. of the auxiliary layer is higher than the Curie point of the auxiliary thermomagnetic recording layer, the auxiliary layer does not show phase transition on erasing nor assists erasing. By this constitution, the range of laser power threshold used for recording and erasing is widened, and moreover, the magnetic field required for initialization can be reduced.
