We detected bits sized at 0.237 μm bit length and 0.85 μm track pitch recorded by magnetic field modulation on a magneto-optical disk with a 690-nm laser diode and 0.60-numerical-aperture-objective using a partial-response maximum-likelihood detection method. We confirmed that the optimum partial-response for this high linear density had four coefficients of 1 by analyzing difference metrics of error critical paths. The recorded bits with areal density of 5.6 bit/μm^2 were also detected at a low error rate, which combination is 0.237-μm bit length and 0.75-μm track pitch. Its write power tolerance is limited to ±22%.
