Abstract
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.
