    • A method is described for writing an optical disc (2) having a multi-layered storage space (30) comprising at least a first storage layer (31) and a second storage layer (32) below the first layer (31). The method comprises the step of preventing a write operation to a portion of the second storage layer (32) located below a maiden portion of said first storage layer (31).In one embodiment, all blocks (40) which are physically located in the second storage layer (32) are incorporated in a defect list (DL) until a sufficiently large portion of the first storage layer (31) has been written at least once.In another embodiment, all blocks (40) which are physically located in the second storage layer (32) are covered by a system file with a predetermined name (“DUMMY”) until a sufficiently large portion of the first storage layer (31) has been written at least once.
    • 描述了一种用于写入具有至少包括第一层(31)下面的第一存储层(31)和第二存储层(32)的多层存储空间(30)的光盘(2)的方法。 该方法包括防止对位于所述第一存储层(31)的第一部分下方的第二存储层(32)的部分的写入操作的步骤。 在一个实施例中,物理上位于第二存储层(32)中的所有块(40)被并入到缺陷列表(DL)中,直到第一存储层(31)的足够大的部分已被写入至少一次。 在另一个实施例中,物理上位于第二存储层(32)中的所有块(40)被具有预定名称(“DUMMY”)的系统文件覆盖,直到第一存储层(31)的足够大的部分具有 至少写了一次。
