    • The present invention relates to a recording apparatus, record carrier and method of recording data on at least two layers of a recording medium by using a radiation power, wherein individual recording speeds are determined for respective ones of the at least two layers at different values of the radiation power. A recording speed to be used for recording on an individual one of the at least two recording layers is selected based on a maximum radiation power specified for the recording operation, and the speed of the recording operation is controlled individually for each of the at least two layers based on the selected recording speed. The determination of the individual recording speeds at different radiation power values may be written or embossed on the record carrier. Furthermore, a recording sequence used for recording on the recording layers can be set based on the sensitivities and thus recording speeds. Thereby, total recording time can be minimized for multi-layer recording media.
    • 本发明涉及一种通过使用辐射功率在至少两层记录介质上记录数据的记录装置,记录载体和方法,其中针对所述至少两个层中的不同值确定各个记录速度 辐射功率。 基于为记录操作指定的最大辐射功率来选择用于记录在至少两个记录层中的单个记录层上的记录速度,并且对于至少两个记录层中的每一个单独地控制记录操作的速度 基于所选记录速度的层。 在不同辐射功率值下的单个记录速度的确定可以被写入或压印在记录载体上。 此外,可以基于灵敏度和因此记录速度来设置用于记录层上的记录的记录顺序。 因此,对于多层记录介质,总记录时间可以最小化。
