Abstract: <P>PROBLEM TO BE SOLVED: To provide an optical pickup device which can reduce the number of optical parts by using holograms, can reduce the cost of products by making the continuous use of an existing photodetector possible, and can materialize downsizing and slimming by constituting the optical parts as one module.  <P>SOLUTION: An opening communicatively connected to the outside is disposed in a lead frame and a two-wavelength light source module for projecting two beams having wavelengths varying from each other into the direction of the optical disk is installed on one side of the opening. A hologram optical element is installed in the upper part of the two-wavelength light source module and hologram patterns to diffract all of the beams reflected from an optical disk are formed atop the hologram optical element. Hologram patterns for wave front compensation which transmit one of the two beams having the wavelengths different from each other, diffract another and are converged with the two passed beams at one point are formed on the base surface of the hologram optical element. The optical pickup device includes a lead frame package consisting of the one module and a photodetector installed in the lower part of the lead frame package in such a manner that independent separating movements can be made.  <P>COPYRIGHT: (C)2004,JPO
