A device for recording information in a track on a record carrier writes and reads marks and spaces each having a nominal run length. The device has a detection unit (32) for generating a signed deviation value signal (34) indicative for a position deviation of a starting edge of a mark and/or an ending edge of a mark with respect to a nominal, position of said edge. A calculation unit (31) selects at least one predefined run length pattern and determines a correction signal (33) based on at least one statistically calculated parameter of the signed deviation value signal for the selected run length pattern. A radiation source control unit (29) controls the power of the radiation source during said writing based on the correction signal.
(ZH) 用来在记录载体上的轨道中记录信息的设备对标记和间隔进行写入和读取,标记和间隔中的每一个均具有标称游程长度。该设备具有产生带符号的偏移值信号(34)的检测单元(32),所述信号(34)表示标记的起始边缘和/或标记的终止边缘相对于所述边缘的标称位置的位置偏移。计算单元(31)选择至少一个预定的游程长度图案,并根据所选择的游程长度图案的带符号的偏移值信号的至少一个统计计算的参数确定校正信号(33)。辐射源控制单元(29)根据所述校正信号,在所述写入期间,控制所述辐射源的功率。
