The minimum signal has a length of SL, and the minimum recorded mark corresponding to the minimum signal has its maximum width of MW, and EW is 0.1 MW. The position on the leading edge side of the recorded mark at the width of EW is designated effective leading edge. The position on the trailing edge side of the recorded mark at the width of EW is designated effective trailing edge. The distance between the effective leading edge and the effective trailing edge is designated effective length ML. And the distance between the effective leading edge and the position at which the width starts to decrease on the trailing edge side is designated WL.
