Abstract
A light beam modulating and deflecting system used to record and read out information by scanning with a light beam wherein modulated power is supplied to at least one light source on a rotating body by use of a fixed primary coil on a stationary substrate and a rotatable secondary coil secured to the rotating body, which coils can maintain electromagnetic coupling therebetween. The light beam is deflected by the rotation of the rotating body and modulated by the drive current for the light source.
