PURPOSE: An optical outputting module and interchangeable optical pick-up device using the module provides a first and second light source in an optical module and use a monitoring optical detector for a plurality of wavelengths, thereby reproducing the number of assembling process and simplifying a wire. CONSTITUTION: An optical outputting module comprises a base(51), a first and second light source(61,63) disposed on the base to radiate laser beams respectively having a different wavelength range, a beam splitter(65) for diverging light radiated from the first and second light source, and a monitoring optical detector(67) for receiving the light radiated from the light source and diverged from the beam splitter and monitoring an optical output of the first and second light source. An interchangeable optical pick-up device using the module comprises the optical outputting module, an object lens disposed on an optical route between the optical outputting module and a recording medium to concentrate the light from the first and second light source on the optical recording medium, a unit for changing an optical route disposed the optical route between the optical outputting module and the object lens to change a passage of incident light, and an optical detector for receiving the light inputted through the unit for changing an optical route. |
