IPC: G11B7/09
Filed: 1989-01-19
Abstract: PURPOSE:To reduce tracking sensor offsetting by using plural piezoelectric elements, independently driving them, and controlling the position of a reflecting mirror. CONSTITUTION:A reflecting mirror 7, which guides light beams 3 emitted from a fixed optical system 2 toward a optical disk 4, a condensing means 5, which condenses the light beams 3 on the optical disk 4, and a correcting means, which detects dislocation in the tracking direction of a condensing spot, dislocates a reflecting mirror 7 according to a detected quantity and corrects the position of the condensing spot, are provided. The correcting means has plural piezoelectric elements 21a and 21b to hold the reflecting mirror 7, and it independently drives the piezoelectric elements 21a and 21b. Consequently the displacement quantity of the respective piezoelectric elements 21a and 21b is suitably selected, and the reflecting mirror 7 can be driving-controlled around an arbitrary position as a rotation center. Thus the forward path and backward path of the light beams 3 can be made correspond, and the offsetting of the tracking sensor signal obtained in the fixed optical system can be suppressed to a small value.

Then, B<+> is ion-implanted onto the Si 24 with the film 27 as a mask, thus changing it into a poly Si 24'. Al's 28 and 28' are vapor-deposited and the Al 28 is removed with the film 27. The Si 24 is etched with the film 25 and the Al 28' as a mask. At this time, the Si 26 on the film 25 is simultaneously etched. Thereafter, the Al 28' on the Al 24' is removed. Thereby, it follows that the Si 24 becomes kept away from the Si 14' at a distance of 1mum or less. An oxide film 29 is formed with the film 25 as a mask. As a result, the Si's 24 and 24' are completely isolated by the film thickness of the film 29.
