    • PURPOSE: An optical disc and an optical disc apparatus are provided to make an address data detector simpler in detecting address data in a case that the address data is recorded in tracks of an optical disc. CONSTITUTION: A disc forms data record areas where tracks, formed by grooves and lands, are alternately arranged in a radial direction. Each groove forms address data record areas for recording the address data by using both wobbles with the same shape. Each groove includes plural address data recording areas(6a-6c) and an address selection data recording area(5). The plural address data recording areas(6a-6c) are arranged along a direction of tracks. The address selection data recording area(5), arranged at a position before the address data recording areas(6a-6c), selects one among the plural address data.
    • 目的:提供光盘和光盘装置,以便在将地址数据记录在光盘的轨道中的情况下,使地址数据检测器更易于检测地址数据。 构成:光盘形成数据记录区,其中由凹槽和焊盘形成的轨道沿径向交替布置。 每个凹槽通过使用具有相同形状的两个摆动形成用于记录地址数据的地址数据记录区域。 每个凹槽包括多个地址数据记录区域(6a-6c)和地址选择数据记录区域(5)。 多个地址数据记录区域(6a-6c)沿轨道的方向排列。 布置在地址数据记录区域(6a-6c)之前的位置处的地址选择数据记录区域(5)在多个地址数据中选择一个。
