ABSTRACT:
An electric charge recording/reproducing apparatus for focusing an electromagnetic radiation ray containing a recording object information signal onto a photoconductive layer member (PCL) in an electric charge image recording medium (D) comprising a laminate of at least an electric charge retention layer, member (CHL), photoconductive layer member (PCL) and a first electrode (E) using an objective lens (318) which is driven and displaced in an optical axis direction by an actuator (ACT) of an automatic focusing system; and to integratedly connect and fix a moving electrode (Em) onto the objective lens (318), the moving electrode (Em) being intended to generate an electric field for positioning the electric charge image recording medium (D) in the electric field of a predetermined electric field intensity, towards the electrode in, the electric charge image recording medium (D). The electric charge image recording medium (D) composed of a laminate of at least a first electrode (E), a photoconductive layer member (PCL), an optical modulation layer member (PML) and an electric charge retention layer member (CHL), the electric charge recording medium comprising said electric charge retention layer member (CHL) provided with an electric charge image pattern for tracking control recorded and formed.
