Abstract:
(EN) Provided are a device and method for enabling high-quality data playback in which crosstalk is eliminated, from a high-density recording-type optical disc. The present invention is provided with: a photodetector which outputs a read signal from a playback track of an information recording disc; a unit for supplying adjacent track playback binarized signals which outputs binarized signals (binary data), i.e. playback signals of adjacent tracks to the playback track; a multi-input adaptive equalizer which is provided with equalizer units for respectively inputting the read signal from the playback track, and the adjacent track playback binarized signals, and which uses adaptive equalization processing based on the input signals to output an equalized signal; and a binarization processing unit which executes binarization processing based on the equalized signal, to generate a playback signal of the playback track.
(FR) L’invention concerne un dispositif et un procédé permettant une lecture de haute qualité de données, dans laquelle la diaphonie est éliminée, à partir d’un enregistrement à haute densité de type disque optique. La présente invention comprend : un photodétecteur qui produit un signal de lecture issu d’une piste de lecture d’un disque d’enregistrement d’informations ; une unité de fourniture de signaux binarisés de lecture de pistes adjacentes, qui émet des signaux binarisés (données binaires), c’est-à-dire des signaux de lecture des pistes adjacentes à la piste de lecture ; un égaliseur adaptatif multi-entrées qui comprend des unités d’égaliseur servant à entrer respectivement le signal lu issu de la piste de lecture et les signaux binarisés de lecture de pistes adjacentes, et qui utilise un traitement d’égalisation adaptative basé sur les signaux d’entrée pour produire un signal égalisé ; et une unité de traitement de binarisation qui exécute un traitement de binarisation basé sur le signal égalisé, afin de générer un signal de lecture de la piste de lecture.
(JA) 高密度記録型光ディスクからクロストークを除去した高品質なデータ再生を可能とした装置、方法を提供する。情報記録ディスクの再生トラックからの読み出し信号を出力するフォトディテクタと、再生トラックの隣接トラックの再生信号である2値化信号(バイナリデータ)を出力する隣接トラック再生2値化信号供給部と、再生トラックからの読み出し信号と、隣接トラック再生2値化信号を各々入力するイコライザユニットを有し、入力信号に基づく適応等化処理により等化信号を出力する多入力適応イコライザと、等化信号に基づく2値化処理を実行して、再生トラックの再生信号を生成する2値化処理部を有する。
