Abstract
The invention relates to a method and a device for producing a scanning device, also termed a pick-up, for optical recording media, which can be produced with a low outlay and thus cost-effectively, and in comparative terms has a low tilt of the objective lens and improved guidance properties. According to the invention, during the connection of an objective lens holder and actuator base plate, a prestress is applied to wires provided as elastic support of the objective lens holder on an actuator base plate. Scanning devices produced according to the invention for optical recording media have a low tilt of the objective lens and improved guidance properties.
