Title (EN) SIGNAL RECORDING/REPRODUCING DEVICE
(FR) DISPOSITIF D"ENREGISTREMENT/REPRODUCTION DE SIGNAUX
Abstract: front page image
(EN)A device for recording/reproducing optionally audio, image or like information signals with high density, using a recording medium with a simplified structure by utilizing a semiconductor layer. The device includes a semiconductor layer (1), an insulator layer (2) formed on the semiconductor layer (1) which has a charge-storing function, signal recording means wherein a conductive recording head (4) supplied with signals to be recorded is relatively moved on the insulator layer (2) and injects electric charges into the insulator layer (2), and signal reproducing means wherein a conductive reproducing head (7) is relatively moved along the recorded tracks on which signals are recorded by the signal recording means and detects variations in the electric properties of the semiconductor layer (1) which are caused by the recorded signals.
(FR)Dispositif d"enregistrement/reproduction de signaux d"images, audio ou autres signaux d"information avec une forte densite, en utilisant un support d"enregistrement a structure simplifiee a l"aide d"une couche a semi-conducteur. Le dispositif comprend une couche a semi-conducteur (1), une couche isolante (2) formee sur la couche a semi-conducteur (1) qui possede une fonction de stockage de charge, des moyens d"enregistrement des signaux ou une tete d"enregistrement conductrice (4) alimentee en signaux a enregistrer se deplace relativement sur la couche isolante (2) et injecte des charges electriques dans la couche isolante (2), et des moyens de reproduction de signaux ou une tete de reproduction conductrice (7) se deplace relativement le long des pistes d"enregistrement sur lesquelles les signaux sont enregistres par les moyens d"enregistrement de signaux et detecte les variations des proprietes electriques de la couche a semi-conducteur (1) dues aux signaux enregistres.
