Abstract:
PURPOSE: To obtain an optical information recording and reproducing device where the number of parts constituting an optical head is reduced, and where a movable part is made small in size and light in weight and highly rigid.
CONSTITUTION: An electric circuit means 5A and a light reflection means 4A are integrally formed on the surface of a lens holder 7A holding an objective lens 1 and coils for driving 2a, 2b and 3. A luminous flux 17 emitted from a light emitting means 13 provided on a fixed base 15 is reflected by a light reflection means 4A and made incident on a photodetector 14 provided on the fixed base 15 so as to detect the position of the lens holder 7A based on an output signal from a photodetector 14.
