摘要:
The present invention provides an optical pickup device employing a disc protector that includes a plurality of first protrusions and at least one second protrusion disposed on the lens holder, wherein the first protrusions are formed by applying a first adhesive to a plurality of areas of a top surface of the lens holder, wherein the first protrusions are arranged at different locations in the tracking direction such that the objective lens is sandwiched between the first protrusions, wherein the at least one second protrusion protrudes is formed by applying a second adhesive to at least one area of the top surface of the lens holder, and wherein tips of the first protrusions are closer to the optical disc than a tip of the at least one second protrusion.
