摘　　要：PtCo/TbFeCo ferro-/ferri-exchange coupled double layer film （ECDL） was fabricated for high density magnetooptical （MO） data storage. At room temperature （RT）, the PtCo film is in-plane magnetized and acts as a mask layer. However, at elevated temperature, it turns to be out-of-plane magnetized because of the strong exchange coupling interactions with the TbFeCo layer. Therefore, this ECDL film has a magnetically induced superresolution （MSR） effect. Combining it with the good Kerr signal at short wavelength, the PtCo/TbFeCo film can be a good candidate for blue laser-MSR MO data storage.PtCo/TbFeCo ferro-/ferri-exchange coupled double layer film （ECDL） was fabricated for high density magnetooptical （MO） data storage.
