“…The introduction of maximum-likelihood detection [12] heralded an era of digital detection with more accurate equalization and ultimately multistate Viterbi detectors capable of accounting for signal-dependent noise and nonlinear distortion [13]. The error-correction schemes quickly evolved to employ Reed-Solomon codes universally.…”

“…The class IV partial response signaling for data detection was first applied to magnetic recording. [13][14][15][16][17] On the other hand, the OFDM has been adopted as a technology used for information transmission, for example, through a digital TV broadcast, a communication technology used for mobile telephones or wireless LANs.…”

The main topic in the telecommunication field is to increase the capacity of information transformation with a limited channel bandwidth. Since the readout and recording bandwidths are also limited in optical disc systems, many technologies in communication systems should be applied to them. In this study, two examples of such technologies, orthogonal frequency division multiplexing (OFDM) and divergence detection methods, were applied to optical disc systems to achieve a higher recording density. I studied optical disc recording and reproduction using the OFDM method, and showed the sample calculation of an approximately 1.5-fold recording density for a BDXL™ system using 5-band multiplexing and 64-quadrature amplitude modulation (64-QAM). Typically, optical disc systems have additional readout channels for objective lens control signals.A dual-phase partial response (PR) signal detection method is demonstrated using an additional signal called tangential push-pull. The calculation result of the method indicates a smaller normalized two-dimensional signal deviation than that of the conventional PR detection method.
