摘要： The invention relates to a method for generating a primary binary signal having a predetermined spectral shape in a predetermined frequency range, in particular having a notch in the power spectrum in a predetermined frequency range. In order to avoid crosstalk between a primary binary signal and a secondary binary signal it is proposed according to the invention that data-words are modulated into channel-words forming the channel bitstream of the primary binary signal and that the modulation of the data-words is chosen such that the predetermined spectral shape of the channel bitstream of the primary binary signal is achieved by using an evaluation criterion based on a spectral weight function the shape of which is tailored to the spectral extent of the channel bitstream of a secondary binary signal. The invention is in particular useful for generating a primary binary signal which is used in the lead-in area of an optical record carrier where a wobble is used in the secondary binary signal for storing a wobble key. The invention relates further to a device for generating the channel bitstream of a primary binary signal, to a primary binary signal and to a record carrier for storing such a binary signal.

摘要： An information system according to the invention comprises a record carrier and a playback apparatus. The record carrier has information marks along a track thereof and exhibits first variations caused by existence and nonexistence of the information marks along the track. The first variations represent an information signal recorded on said record carrier. The record carrier further exhibits second variations caused by variations associated with the information marks. The phase of the second variations is coupled to the phase of the first variations.

摘要翻译： 本发明涉及一种用于在预定频率范围内产生具有预定频谱形状的主二进制信号的方法，特别是在预定频率范围内具有功率谱中的陷波。 为了避免主二进制信号和二次二进制信号之间的串扰，根据本发明提出数据字被调制成形成主二进制信号的信道比特流的信道字，并且数据字的调制 被选择为使得主二进制信号的信道比特流的预定频谱形状通过使用基于频谱加权函数的评估标准来实现，该频谱加权函数的形状被定制为辅助二进制信号的信道比特流的频谱范围。 本发明特别有用于产生在光学记录载体的导入区域中使用的初级二进制信号，其中在辅助二进制信号中使用摆动来存储摆动键。 本发明进一步涉及一种用于产生一个二进制信号的信道比特流，一个二进制信号和一个用于存储这种二进制信号的记录载体的装置。
