Human nongastric H,K-ATPase: Structural properties and transport functions of ATP1al1 assembled with different β β β β subunits

The magneto-optical recording medium, including a transparent polycarbonate substrate, an interference layer made of SiN, a reading layer made of GdFeCo, a recording layer made of TbFeCo, an oxidation-preventing layer made of SiN, a irradiation layer made of Al and an ultraviolet-setting plastic layer, is disclosed. Each layer is deposited to a suitable thickness in the above-named order on the transparent polycarbonate substrate. The composition of each element in the reading layer and the recording layer is set to a suitable value to achieve acceptable characteristics. A high recording and reading density is achieved.
