We have studied high-density magneto-optical recording using a Domain Wall Displacement Detection medium with a 664-nm wavelength laser diode and a 0.60-NA objective lens. Employing a wide-land structured disk and 16 - 17 modulation code, large recording/readout tolerances were obtained with a linear recording density of 0.11 micrometers /bit and an user data-transfer rate of 21 Mbit/sec. Furthermore, the feasibility of higher user data-transfer rate up to 50 Mbit/sec was studied.
