用于对多层光盘进行写入的方法和设备
Abstract:
本发明描述了一种对具有多层存储空间(30)的光盘(2)进行写入的方法，所述光盘至少包括第一存储层(31)和位于第一层(31)下方的第二存储层(32)，所述方法包括禁止在所述第一存储层(31)的未写入部分之下的所述第二存储层(32)的部分上进行写操作的步骤。在一个实施方式中，物理上位于第二存储层(32)的所有数据块(40)都并入到缺陷列表(DL)中，直到第一存储层(31)的足够大的部分已经写入过至少一次。在另一实施方式中，物理上位于第二存储层(32)的所有数据块(40)都被具有预定名称(“DUMMY”)的系统文件覆盖，直到第一存储层(31)的足够大的部分已经被写入过至少一次。
Abstract(English):

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.
