摘要： The present invention relates to a writing scheme for writing an information to an optical recording medium by forming mark areas, e.g. pit areas, corresponding to a predetermined state of said information on a recording surface of said optical recording medium. The writing scheme is adapted to modulate the shape of said mark areas in a predetermined manner so as to obtain incomplete mark areas which do not fully cover the size which is allocated to the channel bit to be written. Thereby, the problem of folding can be prevented or alleviated during the writing or mastering process due to the fact that the incomplete mark areas, e.g. pit effects, do not form large mirror surfaces when combined in clusters of adjacent pits. The incomplete mark areas may be obtained by modulating their shape in any manner suitable to reduce the reflection surface and/or to increase diffraction. Additionally, a multi-level modulation or a binary modulation may be achieved by controlling the shape or number of the incomplete mark areas, respectively, in accordance with the level of a multi-level coded information.

摘要： The present invention relates to an encoding apparatus and method for encoding a source bitstream into a channel bitstream and to a corresponding decoding apparatus and method for decoding a channel bitstream coming source data of a source bitstream, which has been ECC and RLL encoded into said channel bitstream. To avoid any error propagation that might be caused by the insertion of control bits into a user bitstream (after ECC encoding and prior to RLL encoding) between the as-detected RLL input words at the output of the RLL decoder and the ECC symbols, it is proposed to insert control bits with predetermined values into the source bitstream (S10) prior to ECC encoding, rather than after ECC encoding into the user bitstream as it is common practice. After ECC encoding (yielding the user bitstream (U10) of encoded ECC symbols) and prior to RLL encoding (yielding the channel bitstream (C11)) the control bits (x) in the user bitstream may be set to any values that suit the realization of the desired property of the channel bitstream. In the corresponding decoding apparatus, after RLL decoding and prior to ECC decoding, the as- detected control bits are set back to their known predetermined values.

摘要： Presently known codes have long trains consisting of consecutive 2T runs that reduce the performance of the bit detector. By using a code with an RMTR constraint of 2 an improvement in the bit detection is achieved. A code constructed in a systematic way that provides an RMTR constraint of 2 is presented. Several variations of such a code are disclosed where one or more sub-codes are used, where coding states are divided into coding classes ordered according to more or less stringent constraints on leading bits and where code words are divided into code word types ordered according to more or less stringent constraints on trailing bits. Then, for a given sub-code, an code word of type t can be concatenated with an code word of the next sub-code if said subsequent code word of said next sub-code belongs to one of coding states of the coding class with index T max +1 - t .

摘要： ABSTRACT: 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 ( Š + , Š - ) which circuit suppresses cross-talk of the main track present in the satellite signals (S + ,S - ) by minimizing a correlation between the satellite signals (S + ,S - ) and the read signal (C), the improved satellite signals ( Š + , Š - ) being subsequently fed to the first circuit which is arranged to suppress the cross-talk of the read signal (C) by minimizing a correlation between the improved read signal ( Č ) and the improved satellite signals ( Š + , Š - ).

摘要： The present invention relates to a coding strategy for joint modulation coding and ECC coding. It relates in particular to the situation where 2D coding is performed along one-dimensionally evolving strips containing a number of bit rows in the radial direction of the strip, which is orthogonal to the former direction. The idea further relates to high-rate modulation coding. According to the invention, a strip is built up by an alternation of two basic sub-units, each with their own modulation code. The first sub-unit comprises a larger number of bit rows, and its (high-rate) modulation code has a high coding efficiency realized through the use of large codewords. The second sub-unit comprises a single or only few bit rows, and its modulation code has a lower efficiency, which makes it much less sensitive to error-propagation: another function of the sub-unit of the second type is to glue sub-units of the first type together while maintaining the 2D constraint also at the boundaries of the subunits of the first type. The first sub-unit relates to most or all of the source data, and is encoded first, prior to ECC coding. The second sub-unit relates to the ECC parities, and possibly the remainder of the source data. Both at the encoder and the decoder, special measures are taken related to the precise order of both modulation code encoders (and decoders), and of the ECC encoder (and decoder).

摘要： The present invention discloses an optical drive and a method for preprocessing a disc readout signal r k of an optical drive on the basis of a set of low-pass filters. The cutoff frequency f c of the filters wk, more particularly, can be set within the optical bandwidth, which improves the Viterbi detection performance in the case of high speed drive operations. Three types of filters are described, in which a Type I shaping filter performs best given a limited hardware cost for the bit detector. Compared to other more advanced noise- whitening techniques, it is only speed dependent and requires little prior knowledge of the channel and noise, thus cheap and easy to design. The invention can be applied in connection with optical disc drives, in particular when high frequency noises are dominant, for example, in the case of high speed operations.
