    摘要： An offset amount measuring method is provided with: a recording process for measurement (i) of recording information for measurement, into a recording track in the L0 layer, by a predetermined section, from a measurement reference position, and of (ii) recording the information for measurement, into a recording track in the L1 layer, by the predetermined section, from or toward a measurement correspondence position, which is associated with the measurement reference position by the pre-format address; a first detecting process of detecting a border of a first recorded area in which the information for measurement is recorded and a first unrecorded area in the first recording track, on the basis of a difference in reflectance between the first recorded area and the first unrecorded area; a second detecting process of detecting a second border position in the recording track in the L1 layer, on the basis of a difference in reflectance; and a determining process of determining the offset amount, on the basis of the detected first and second border positions. Moreover, it is also provided with a judging process of judging whether or not the determined offset amount is within tolerance with respect to the first offset amount set in advance for offset countermeasures.

    摘要： A groove track and a land track are alternately and spirally formed on an information recording medium. On the land track neighboring the groove track, pre-information indicating position information of a track on a disc is formed as a prepit. On the information recording medium, an embossed area is formed so that information about a copyright and for preventing an illegal copy cannot be rewritten. In the embossed area, an embossed configuration including a pit and a space of predetermined depths is formed. The prepit in the embossed area is formed so that the prepit has an optimized configuration according to a pit length and a space length in the embossed area which the prepit neighbors. Consequently, interference between the embossed configuration and the prepit can be prevented even in a case that the prepit is formed in addition to the embossed configuration in the embossed area.

    摘要翻译： 凹槽轨道和脊轨道交替地并螺旋地形成在信息记录介质上。 在与凹槽轨道相邻的陆地轨道上，指示盘上的轨道的位置信息的预先信息被形成为预凹坑。 在信息记录介质上，形成压花区域，使得关于版权和防止非法复制的信息不能被重写。 在压纹区域中，形成包括凹坑和预定深度空间的压纹构造。 形成压纹区域中的预凹坑形成为使得预凹坑具有根据凹坑长度和预凹坑邻近的压纹区域中的间隔长度的优化配置。 因此，即使在浮雕区域中除了压花构造之外还形成预凹坑的情况下，也可以防止压花构造与预制坑之间的干涉。
