Abstract
High density magneto-optical recording was realized with the combination of a compact green laser and a very sensitive NdTbFeCo/TbFeCo MO disk for the wavelength of 532 nm. This media has a high Kerr rotation angle at 532 nm and maintains a stable recording domain. With an objective lens of 0.6 NA, CNR of 48 dB and jitter of 3.0 nsec by mark edge recording was obtained for a mark length of 0.45 micrometers (0.34 micrometers /bit) at a writing power of 4.5 mW.
