Title (EN) MAGNETIC RECORDING/REPRODUCING DEVICE
(FR) DISPOSITIF D'ENREGISTREMENT/REPRODUCTION MAGNETIQUE
Abstract:
(EN) In order to obtain an excellent sound quality and excellent picture quality which is free from crosstalk from a track adjacent to a target track by preventing a Hi-Fi head from picking up a third track from the target track and in order to effect a special reproduction without using a field memory in a long time recording mode which provides five or more times the recording time of a standard recording mode without reducing the track pitch of the Hi-Fi head in a magnetic recording/reproducing device, when an image in the long time mode of five or more times is recorded, a pair of standard/triple-mode double-azimuth system heads are used for recording, a head which is exclusively for reproduction and has a head width smaller than the width of the recording track is provided and, further, 4 heads of conventional double-azimuth system are used.
(FR) Afin d'obtenir une excellente qualité audio et une excellente qualité d'image exempte de toute diaphonie provenant d'une piste adjacente à une piste cible, en empêchant une tête Hi-Fi de capter une troisième piste à partir de la piste cible, et afin de réaliser une reproduction spéciale sans utiliser de mémoire de champ en mode d'enregistrement long, représentant au moins cinq fois le temps d'enregistrement d'un mode d'enregistrement standard, sans réduire le pas transversal entre les pistes de la tête Hi-Fi dans un dispositif d'enregistrement/reproduction magnétique, lors de l'enregistrement d'une image en mode long égal à au moins cinq fois le mode standard, on utilise une paire de têtes de système à double azimut en mode triple/standard, pour l'enregistrement, on monte une tête qui est prévue exclusivement pour la reproduction et dont la largeur est inférieure à la largeur de la piste d'enregistrement et on utilise, en outre, quatre têtes de système à double azimut classique.
