摘要： An optical disk has a rewritable first recording area and a read-only second recording area. The first recording area includes first tracks composed of groove tracks and land tracks formed on an optical disk substrate alternately in a spiral or concentric shape. Each of the first tracks is divided into a plurality of first sectors, and each of the first sectors includes a first header region having identification data for identifying the first sector and a first data region for recording user data by forming recording marks by changing optical characteristics of a recording surface. The second data recording area includes second tracks formed with physical concave and convex shaped pit rows arranged on the optical disk substrate in a spiral or concentric shape. Each of the second tracks is divided into a plurality of second sectors, and each of the second sectors includes a second header region having identification data for identifying the second sector and a second data region having read-only data recorded as the pit rows. The first header region includes a physical concave and convex shaped first pit row. Each pit of the first pit row has a width in a radial direction of the optical disk substantially equal to a width of the groove track and is wobbled outward or inward from a center line of the groove track by about a quarter of a pitch of the groove track. The second header region includes a physical concave and convex shaped second pit row. Each pit of the second pit row has a width in the radial direction of the optical disk smaller than the width of the groove track and is formed substantially along the center line of the second track.

摘要： An optical disc which has a rewritable first recording region and a read-only second recording region. The first recording region has first tracks which are composed of group tracks and land tracks which are alternately provided on a disc substrate spirally or concentrically. Each first track is divided into a plurality of first sectors. Each first sector has a first header region where identification data by which the first sector is identified are recorded and a first data region in which user data are recorded with recording marks where the optical characteristics of the recording surface are changed. The second recording region has second tracks which are composed of a physical pit row which are provided on the disc substrate spirally or concentrically. Each second track is divided into a plurality of second sectors. Each second sector has a second header region where identification data by which the second sector is identified are recorded and a second data region in which read-only data are recorded by means of the pit row. The first header region includes a first physical pit row. Each pit of the first pit row has a width in a radial direction of the disc which is substantially equal to the width of the group track and, further, the pits are staggered along the center line of the group track radially with pitches of approximately a quarter of the pitch of the group track. The second header region includes a second physical pit row. Each pit of the second pit row has a width in a radial direction of the disc which is smaller than the width of the group track and, further, the pits are arranged generally along the center line of the second track to be tracked.
摘要翻译：光盘具有可重写的第一记录区域（5）和只读（2,3）的第二记录区域。第一记录区域（5）包括以螺旋或同心形状交替地形成在光盘基板上的凹槽轨道和槽脊轨道构成的第一轨道。每个第一磁道被分成多个第一扇区，并且每个第一扇区包括具有用于识别第一扇区的标识数据（11a，11b）和用于记录用户数据的第一数据区（17）的第一标题区通过改变记录表面的光学特性来形成记录标记。第二数据记录区域包括以螺旋或同心形状布置在光盘基板上的物理凹凸阵列形成的第二轨迹。每个第二磁道被分成多个第二扇区，并且每个第二扇区包括具有用于识别第二扇区的标识数据（31）和具有记录为凹坑的只读数据的第二数据区的第二标题区行。第一标头区域包括物理的凹凸形状的第一坑排。第一凹坑列（21a，21b）的每个凹坑的宽度在光盘的径向方向上基本上等于凹槽轨道的宽度，并且从凹槽轨道的中心线向外或向内摆动大约四分之一的凹槽轨道的间距。第二头部区域包括物理凹凸形状的第二凹坑排（29）。第二凹坑列的每个凹坑具有比光盘的径向小的宽度，并且沿着第二轨道的中心线形成。

摘要： Even if an authorized second-generation copy of a production is illegally recorded on a recording medium, the copy cannot be reproduced. When a copy of a production is recorded on a disk, medium identification information recorded in the BCA on the disk is embedded as a watermark. When the copy is reproduced, the medium identification information recorded in the BCA is collated with the medium identification information embedded in the copy as an electronic watermark. Only when the both agree with each other, reproduction is performed.
