PURPOSE: To enhance working efficiency and to reduce a production cost by molding coils for focusing substrates A and coils for tracking on substrates B, mounting the substrates A, B to a moving body and omitting the operations of winding coils on this moving body.

CONSTITUTION: The moving body 8 which holds an objective lens 7 for irradiation of an optical information recording medium with a laser beam at the center is supported by means of a leaf spring to a fixing body having a magnetic circuit consisting of a magnet and yoke movably vertically. The coils 9a, 9b are provided on the substrates 10a, 10b for focusing and the coils 12a, 12b are provided on the substrates 13a, 13b for tracking. Plastic plates, etc., are used for the respective substrates 10a, 10b, 13a 13b and the respective coils are formed of printed wirings, etc. The substrates 10a, 10b are mounted to the front and rear surfaces 11a, 11b on the moving body 8 and the substrates 13a, 13b are mounted to the flanks 14a, 14b. As a result, the operations for winding the coils on the moving body 8 are omitted. The working efficiency is thus enhanced and the product cost is reduced.
