ABSTRACT:
A recording condition approximate to the optimal is obtainable for a media even if unknown to the drive. A technique is provided that is effective for improving the signal quality, particularly, at a Wobble and Lpp. By regulating an intermediate pulse condition PWD, Tmp of a recording pulse configured with a top pulse, an intermediate pulse and a last pulse, the pit width W in a saturation code is controlled. The pit length and phase in the saturation code is controlled based on a front phase correction amount Ttop and rear phase correction amount Tlast.
