Abstract: PURPOSE:To efficiently form a lens for condensing at the end face of optical part and to simultaneously form the condenser lens pair of the optical axes aligned to the end faces of the optical parts to be coupled by forming the deposit consisting of the reaction product formed by a photo CVD method. CONSTITUTION:On the exit end face 3 of the optical waveguide 1 formed by the photo CVD method using light 2 guided in the optical waveguide 1 of the optical part of the part 4 to which the light 2 emitted from the optical waveguide 1 is cast, the deposit 5 formed by reaction of a gaseous material 6 formed by the photo CVD method, is formed. The optical waveguide 1, for example, a transparent core layer 1A having a high refractive index in the case of a fiber, is coated with a transparent clad layer 1B having the refractive index lower than the refractive index thereof. The intensity of the light 2 emitted from the exit end face 3 to the outside is the highest in the center when the light 2 is guided to the core layer 1A. Then, the gaseous material 6 is excited by the light 2 shining thereon and the reaction is accelerated at the exit end face 3 of the light 2 when the front end of the optical waveguide 1 is inserted into the photo CVD apparatus and the gaseous material 6 is introduced into the apparatus. The reaction product is thus formed as the lens-shaped deposit 5.

The signals are time division-multiplexed in a time division-miltiplex means 16 and converted to sound signals in one channel. These sound signals are subjected to the processing in a PCM sound signal recording processing circuit 17, then divided into PCM sound signals in two channels again by a switcher 18. These signals are supplied in each channel to a head being time-division-multiplexed with video signals by switchers 12a, 12b, 12c, 12d. Therefore, the recording processing circuits and the reproducing processing circuits can be reduced in number down to one system, hence it contributes in miniaturizing the device and reducing cost.
