    • A method and a device of recording an optical disc are provided to ensure stable reproduction of a high-speed and multi-layered optical disc by removing influence of crosstalk even when a pre-pit signal is not detected during data recording in the optical disc. A recording method of an optical disc includes a step of producing a pre-pit signal(N1) from the optical disc(D); a step of generating a second standard clock signal(N22) from the pre-pit signal; a step of detecting phase deviation of a first standard clock signal(N32) from the second standard clock signal; and a step of compensating the first standard clock signal on the basis of an average value of the detected phase deviation. An optical disc recording device comprises a wobble signal generating unit(30,31), a first standard clock signal generating unit(G1), a pre-pit signal reproducing unit(10), a second standard clock signal generating unit(G2), a deviation detecting unit(60,61), and a compensating unit. The wobble signal generating unit produces a wobble signal(N31) from the optical disc. The first standard clock signal generating unit generates the first standard clock signal from the wobble signal. The pre-pit signal reproducing unit reproduces the pre-pit signal from the optical disc. The second standard clock signal generating unit produces the second standard clock signal from the pre-pit signal. The deviation detecting unit detects a phase deviation of the first standard clock signal by using the second standard clock signal. The compensating unit corrects the first standard clock signal on the basis of the average value of the phase deviation detected by the deviation detecting unit.
    • 提供一种记录光盘的方法和装置,以便即使当在光盘中的数据记录期间未检测到预制凹坑信号时,也可以通过消除串扰的影响来确保高速和多层光盘的稳定再现。 光盘的记录方法包括从光盘(D)产生预凹陷信号(N1)的步骤; 从所述预凹坑信号产生第二标准时钟信号(N22)的步骤; 检测第一标准时钟信号(N32)与第二标准时钟信号的相位偏差的步骤; 以及基于检测到的相位偏差的平均值来补偿第一标准时钟信号的步骤。 一种光盘记录装置,包括摆动信号产生单元(30,31),第一标准时钟信号产生单元(G1),预凹坑信号再现单元(10),第二标准时钟信号产生单元(G2) 偏差检测单元(60,61)和补偿单元。 摆动信号产生单元从光盘产生摆动信号(N31)。 第一标准时钟信号产生单元从摆动信号产生第一标准时钟信号。 预凹坑信号再现单元从光盘再现预凹陷信号。 第二标准时钟信号产生单元从预凹坑信号产生第二标准时钟信号。 偏差检测单元通过使用第二标准时钟信号来检测第一标准时钟信号的相位偏差。 补偿单元基于由偏差检测单元检测到的相位偏移的平均值来校正第一标准时钟信号。
