Optical recording device

摘要

An optical recording device comprising a rigid arm carrying an optical system generating a light beam whose characteristics are varied in response and in relationship to a signal to be recorded. The arm is driven in an oscillatory movement by a motor of circular movement associated to a crank. The device further comprises a recording support unrolled along a direction orthogonal to that of the arm oscillatory movement, and means for synchronizing the control of the optical system with the movement of the arm.
