When the multi-layer disc is read by a normal optical pickup, the signal light that is reflected in the read-out layer contains stray light from the adjacent recording layers, which is called the layer cross-talk (LCT). To reduce the LCT, we developed a new optical pickup that has a segmented wave-plate made of an auto-cloned photonic crystal. It has some advantages of perfect removal of LCT, detection of the high efficiency of the signal light, and the miniaturization of the optical pickup. In addition, by using this optical pickup, we confirmed the improvement of the signal performance, using a HD DVD dual-layer disc that has a thin spacer layer thickness, to increase the LCT.

Multi-level run-length-limited (ML-RLL) modulation on optical storage channels is a promising method to increase the recording density effectively. In this paper, some experimental results of 4-level RLL modulation on digital versatile disc (DVD) read-only discs are firstly presented. A new DC-free 4-ary RLL (2.8) code with code rate of 8/10 (bits/symbol) is designed, and partial-response maximum-likelihood (PRML) detection is used to evaluate the bit error rate (BER) performance of multi-level readout signals. Experimental and simulation results show the feasibility of 4-level RLL modulation on DVD channels

A new radial tilt adjustment method with a partial response signal-to-noise ratio in HD DVD is described. This method can adjust the radial tilt rapidly because it monitors a parameter with polarity related to the radial tilt deviation. The accuracy of the method is plusmn 0.02 deg, which is enough for HD DVD systems

The paper proposed a novel super-RENS ROM disc with a narrow track pitch using a group tracking technique, GTS-super-RENS ROM disc. The group tracking technique enabled to increase capacity in the radial direction up to 1.5 times. Using GTS method, a -20 dB cross-talk from the neighbor pit trains was obtained. It was confirmed that capacity of GTS-super-RENS ROM disc will become a promising method to further increase capacity in super-RENS disc world
