Magnetic Field Modulation Recording on GdDyFeCo Magnetooptical Disk

The characteristics of magnetic field modulation recording on GdDyFeCo magnetooptical disks were investigated. The GdDyFeCo recording layer was deposited by a two-source RF magnetron sputtering method. The thermomagnetic properties of the compositionally modulated films varied with the modulation periodicity, and the recording field (Hs) was smallest at a… CONTINUE READING
