Paper Abstract

A new in-groove format with Saw-Tooth wobble (STW) for blue laser and high NA system is proposed. The STW is designed in order to satisfy for high reliability of the addressing, continuous generation of system clock and easy linking of write data. The format efficiency is high, and moreover, it is confirmed capability for not only single-layer but also dual-layer phase change optical disk. In the conditions of the disk diameter of 120mm, track pitch of 0.32 micrometers and data bit length of 0.116micrometers /bit, the user capacity per layer is achieved 25G-bytes using D8-15 codec and PR(3443)ML channel. The bottom jitter of 9.4 percent by level-slice and the bit-error-rate of 6.0E-6 after PRML are obtained. In addition, the wide stress margins, as the radial/tangential tilt and the defocus tolerances, demonstrate to be enough to realize consumer optical disk systems of the next generation.
