INTEGRATED OPTICAL PICKUP, A FABRICATION METHOD THEREOF AND AN OPTICAL INFORMATION STORAGE DEVICE HAVING THE INTEGRATED OPTICAL PICKUP, CONCERNED WITH REALIZING A MASS PRODUCTION OF AN OPTICAL INFORMATION STORAGE DEVICE AT LOW PRICE

摘要

PURPOSE: An integrated optical pickup is provided to comprise an optical bench forming an optical path, and to separate the optical bench and a condenser/optical path separation member into plural assemblies. CONSTITUTION: Main optical detectors(36a,36b) receive a light reflected from an optical information storage medium(D). A condenser/optical path separation member(37) focuses a light irradiated from a light source(32) on the optical information storage medium(D), and separates optical paths of the incident light of the optical information storage medium(D) and a reflected light of the optical information storage medium(D). An optical bench(31) is coupled with the condenser/optical path separation member(37), and forms an optical path. The optical bench(31) and the condenser/optical path separation member(37) are formed on wafers, respectively, and are separated into plural assemblies.
