Various technique to reproduce magneto optical signals from high-density recorded patterns are reported, for example DWDD, MAMMOS, CAD, etc.In this paper we propose a method with NA 0.85 lens and a 405 nm laser.We search the feasibility of conventional MO media by laser-pulsed magnetic field modulation (LP-MFM) method having a target of high-density 20Gbit/inch^2.We had the method of UV irradiation to suppress the media noise, thermal control layer to prevent the decay of the Kerr rotation angle, and optical phase shift method to reduce the cross-talk.And we could be making sure the feasibility of 20Gbit/inch^2 observing a low error rate of less than 10^<-5> at the bit length of 0.13 μm.
