Abstract
We propose a method to record a multilevel signal onto an optical read only memory disc. In this method, we use the signal processing to generate the multilevel recording signal, which satisfies zero-intersymbol interference condition and zero-direct current condition. The resultant multilevel signal is emboss recorded as position displacement of groove walls. To playback a disc, the push- pull detection and the adaptive equalizer is used. Experimental disc of 0.6 micron trackpitch and a 0.28 micron/bit of density is made. When a DVD equivalent optical pickup is used to playback this disc, we confirm the error rate of 3 X 10-4 and a clear 2D eye pattern of 16 levels.
