    • In modem optical disc systems, inter-track spacing is chosen relatively small in order to allow high storage densities. As a result, the optical spot has a radius comparable with the track pitch, and the data written on neighboring tracks appear in the target track signal in the form of inter-track interference (cross-talk). To tackle the cross-talk problem, cross-talk canceling schemes are normally employed. These schemes use three spots, one spot on the main track and two satellite spots on adjacent tracks. The read signal (C) is improved by minimizing the cross-talk between the satellite signals (S + ,S - ) and the read signal (C). However, due to the decreasing inter-track spacing, the decorrelation concept fails since the satellite spots read too much central track information and become strongly correlated with the read signal (C), which causes "leakage" in the decorrelation. The present invention solves this problem with an additional circuit for outputting improved satellite signals (S +
    • 在调制解调器光盘系统中,为了允许高存储密度,选择相对较小的间隙间距。 结果,光点具有与轨道间距相当的半径,并且写入相邻轨道的数据以轨道间干扰(串扰)的形式出现在目标轨迹信号中。 为了解决串扰问题,通常采用串扰消除方案。 这些方案使用三个点,主轨道上有一个点,相邻轨道上有两个卫星点。 读取信号(C)通过使卫星信号(S SUP),读出信号(C)之间的串扰最小化来改善。 然而,由于轨道间距减小,因为卫星点读取太多的中心轨迹信息并且与读信号(C)强相关,因此解相关概念失败,这导致去相关中的“泄漏”。 本发明通过用于输出改进的卫星信号的附加电路来解决这个问题

    • The present invention relates to a method and apparatus for controlling at least one readout parameter of a magneto-optical domain expansion recording medium. An average detected runlength of the reading signal is monitored, and an error signal is generated on the basis of a comparison of the monitoring result with the predetermined average runlength that has been set during the encoding step. The at least one readout parameter is then controlled by means of the generated error signal. Furthermore, the present invention relates to a method, apparatus and record carrier wherein a runlength constraint is applied to at least one of the following quantities: mark regions and space regions in said storage layer, said runlength constraint being selected to keep an accumulated runlength deviation from a predetermined average runlength within a predetermined range. The proposed runlength property and control scheme provide the advantage that all detected runlengths contribute to the error signal to make the response must faster and to reduce readout errors.

    • A method is disclosed for reading information from an optical disc (2) containing tracks (11, 21) with 2D-SCIPER coded information. The method comprises the steps of: generating at least one light beam (32); focussing the light beam (32) in a focal spot (F) on an information layer of the optical disc (2); controlling the radial position of the focal spot (F) such that the focal spot (F) covers pits (10; 20) of two adjacent tracks (11; 21). The optical centre (42) of the focal spot (F) follows a trajectory (45) which is radially offset with respect to a halfway line (44) at a position exactly halfway between the said two adjacent tracks (11; 21). According to this method, the disturbing non-linear intersymbol­interference is removed from the multi-level eye-pattern of 2D-SCIPER, yielding much better distinguishable signal levels.

    • 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.
