摘要： For (re)writable and read-only optical disc systems the data clock is recovered by a phase locked loop (PLL), where the error signal is generated by comparing the actual zero-crossing with the zero-crossing of the generated clock signal. Given an optical system with a laser wavelength λ laser and a numerical aperture NA, the cut-off wavelength of the Modulation Transfer Function is given by λ 0 = λ laser /(2.NA). With decreasing bit length the amplitude of the minimum wavelength will decrease and is zero for wavelengths below λ 0 . Consequently, the phase error signals generated by zero-crossing of these signals are disturbed by noise. The idea of the invention is to use the zero-crossings with sufficient performance only in deriving phase information for the clock recovery.
摘要翻译：对于（再）可写和只读光盘系统，数据时钟由锁相环（PLL）恢复，其中通过将实际过零与产生的时钟信号的过零比较来产生误差信号。给定具有激光波长衰减器和数值孔径NA的光学系统，调制传递函数的截止波长由λ0= lambdalaser /（2.NA）给出。随着位长度的减小，最小波长的幅度将降低，对于低于λ0的波长，幅度为零。因此，由这些信号过零产生的相位误差信号被噪声扰乱。本发明的思想是仅在导出时钟恢复的相位信息时使用具有足够性能的过零点。

摘要： Domain bloom, also known as asymmetry, is a systematic imperfection caused by the writing process in optical discs. During disc read-out it causes signal transitions to shift with respect to their nominal positions. State-of-the-art equalization and detection methods suffer significant performance losses if directly applied to replay signals with asymmetry. A non-linear model for replay signals with asymmetry is used for new equalization and detection techniques that are applicable to signals in the presence of asymmetry. Modifications are described of the threshold bit-detector, the run-length pushback bit-detector, and the PRML sequence detector, which have significant performance benefits. These benefits come at almost no additional cost with respect to existing detectors.

摘要： The present invention relates to a bit detection method for detecting the bit values of bits of a channel data stream stored on a record carrier, wherein the channel data stream resides on an N-dimensional lattice of bits and comprises a plurality of contiguous bit units, each bit unit comprising at least one bit, wherein bit detection for the channel data stream is performed by an iterative procedure, each iteration being carried out on the basis of said bit units, wherein the bit values of the bits of a bit unit are detected by said iterative procedure based on the received HF signal values of the bits of said bit unit. The proposed method comprises an initialisation step, an updating step and an iteration such the method the bits are detected in an iterative but non-recursive way which allow for a high level of parallel processing in the implementation. In the proposed bit detection method, an evaluation criterion is used which is based on the difference between the received HF-signal and a reference HF-signal for each bit of a bit unit consisting of a plurality of bits, where the reference HF-signal depends on the bit value of the bit to be updated, and on its neighbouring bits, for which bit decisions in a previous iteration step are used. Thus, a high capacity, in particular in two-dimensional optical storage, can be achieved which substantially improves the performance of a threshold detector. Hence, the bit detection method according to the invention does not prohibit implementations aimed for high data-rates.

摘要： The present invention relates to a Viterbi bit detection method for detecting the bit values of bits of a channel data stream stored on a record carrier along an N-dimensional channel tube, N being at least two, of at least two bit rows one-dimensionally evolving along a first direction and being aligned with each other along at least a second of N-1 other directions, said first direction together with said N-1 other directions constituting an N-dimensional lattice of bit positions, comprising application of a row-based one-dimensional Viterbi bit detection method independent for each of the bit rows of said channel tube. To achieve a reliable bit detection a number of independent one-dimensional row-based Viterbi bit detectors, also known as sequence detectors, is used, one for each bit row in the channel tube : the interference between successive neighbouring bit rows is taken into account via the computation of the branch metrics (for the considered bit row), in which local bit decisions on the primary neighbouring bits in the neighbouring rows are used.

摘要： The present invention relates to a method of determining write parameters for recording information on an optical record carrier, said information being in the form of a channel data stream to be recorded as a channel band of at least one symbol row onedimensionally evolving along a first direction, wherein the write parameters are determined by an iterative procedure. In particular for determining pit-hole sizes as the write parameters of pit-bits to be mastered on a ROM disc the proposed method comprises the steps of: setting the write parameters for recording pit-symbols of said channel data stream to preliminary parameter values, updating the preliminary parameter values by searching for the updated parameter values that best fulfil a predetermined criterion for the write parameters for recording of pit-symbols, said criterion being determined by the difference of HF-signal values, which will be determined by use of a channel model or obtained during read-out of pit-symbols recorded by use of the updated parameter values, and reference HF-signal values, - iterating said updating until a predetermined condition is fulfilled. Thus, a pre-compensation of non-linearities of the read-channel at the side of the write-channel can be obtained without the need to use a large write-strategy matrix or table containing a large number of write parameters.
