A method of data reconstruction from a digital magneto-optical disk system with diffraction-limited spot size is described. Using a linear filter with high-frequency enhancement we show that significant improvements in the storage capacity can be achieved at a reasonable cost in terms of the signal-to-noise ratio. Performance is evaluated against an optimum but impractical method as well as a technique for the reconstruction of the analog waveforms.
