• MAMMOS (Magnetic Amplifying Magneto Optical System) is a promising technology for high storage densities towards 100 Gb/<in>^2 in rewriteable optical recording systems. However, the laser power margin for correct readout is quite small. This small margin is explained by a discussion of the readout process. A method is proposed to significantly improve the resolution and power margin by using different run length constraints for marks and spaces. Detailed simulations and experimental results on power margin versus bit length are presented, demonstrating improvements in power margin by a factor of around 3 (at constant density) and an increase in storage density by about a factor of 2 (at constant power margin).
