Title
(EN) METHOD AND APPARATUS FOR RECORDING DIGITAL DATA SIGNAL
(FR) PROCEDE ET DISPOSITIF D'ENREGISTREMENT D'UN SIGNAL NUMERIQUE DE DONNEES
Abstract
(EN)
A method of recording a digital data signal, such as an audio PCM signal, onto a recording medium in the longitudinal direction thereof, together with an apparatus which is suitable for this recording method. Even-numbered words and odd-numbered words in a digital data signal are recorded on a first track group and a second track group, respectively, which are separated from each other in the widthwise direction of a recording medium, to prevent a series of words becoming error words because of, for example, a flaw in the recording medium in the longitudinal direction thereof. The data format is changed at the input and output of a recording encoder to enable an error correction code and a recording circuit to be used in common for digital tape recorders which have different numbers of tracks, e.g., n tracks and 2n tracks. When an error correction code is recorded in such a manner that one word in the digital data signal is divided into a plurality of symbols which are formed into an error correction code, a plurality of symbols of the same word are recorded at a position at which error correlation is strong, making effective use of the error correction capacity of the error correction code.

Procédé d'enregistrement d'un signal numérique de données, tel qu'un signal audio à modulation par impulsions codées, sur un support d'enregistrement dans son sens longitudinal, ainsi que dispositif indiqué pour ce procédé d'enregistrement. Les mots de nombre pair et les mots de nombre impair dans un signal numérique de données sont enregistrés sur un premier groupe de pistes et sur un deuxième groupe de pistes, respectivement, séparés l'un de l'autre dans le sens de la largeur d'un support d'enregistrement, de manière à empêcher une série de mots de devenir erronés à la suite, par exemple, d'une imperfection dans le sens longitudinal du support d'enregistrement. Le format des données est modifié à l'entrée et à la sortie d'un codeur d'enregistrement afin de permettre l'utilisation combinée d'un code de correction d'erreur et d'un circuit d'enregistrement dans des enregistreurs numériques à bande possédant un nombre différent de pistes, par exemple n pistes et 2n pistes. Lorsqu'un code de correction d'erreur est enregistré de sorte qu'un mot dans le signal numérique de données est divisé en une pluralité de symboles formant un code de correction d'erreur, une pluralité de symboles du même mot sont enregistrés en une position à laquelle la corrélation d'erreur est forte, ayant ainsi efficacement recours à la capacité de correction d'erreur du code de correction d'erreur.
