摘要： An optical information recording medium having a plurality of grooves and a plurality of lands alternately formed. Each groove and each land function as recording tracks. The medium includes a first header region having a plurality of first phase pits respectively formed on extensions of the plurality of lands, and a second header region having a plurality of second phase pits respectively formed on extensions of the plurality of grooves. Each groove has an optical depth of about 3null/8 where null is the wavelength of a light beam to be used. Each first phase pit has an optical depth smaller than that of each groove. Each second phase pit has an optical depth substantially equal to that of each groove. The first header region and the second header region are shifted from each other along the extension of each groove.
摘要翻译：一种光学信息记录介质，具有交替形成的多个槽和多个焊盘。每个槽和每个地面作为记录轨道。所述介质包括具有分别形成在所述多个焊盘的延伸部上的多个第一相位凹坑的第一标题区域和分别形成在所述多个沟槽的延伸部上的多个第二相位坑的第二标题区域。每个凹槽的光学深度约为3lambd / 8，其中lambd是要使用的光束的波长。每个第一相位凹坑的光学深度小于每个凹槽的光学深度。每个第二相位凹坑的光学深度基本上等于每个凹槽的光学深度。第一标题区域和第二标题区域沿着每个沟槽的延伸部彼此偏移。
