Abstract
This paper presents the new development of the signal waveform modulation optical disc. The signal waveform modulation optical disc is realized through inserting a sub-pit/sub-land into an original land/pit. More storage states are realized with changing the size and position of the sub-pits/sub-lands, which influence the corresponding readout signal waveforms. Modulation code and its realization are key technologies for signal waveform modulation optical disc. In this study, we employ maximum run transition code and level modulation process as the modulation code of signal waveform modulation optical disc. A 5/6MTR (2, 10) code is designed as the first step of the proposed modulation code, and the level modulation process are used to avoid multilevel on shortest runs. The realization process of the proposed code is presented, and the maximum level numbers for different run-length marks are investigated with the calculated readout signals.
