Filed: 1988-01-27
Abstract: PURPOSE:To set the direction of incident light on an optical disk perpendicularly to an incident plane by providing a hologram lens between a 1/4-wave plate and an objective lens, and rotating the hologram lens corresponding to a quantity of plane shaking detected by an optical detector. CONSTITUTION:Light emitted from a semiconductor laser 1 is changed to a parallel ray at a coupling lens 2. The parallel ray transmits a beam splitter 3, the 1/4-wave plate 4, and the hologram lens 7 sequentially, and is converged on the objective lens 5, and is made incident on the plane 11 of an optical disk 6. The light reflected on the disk 6 transmits the above components in reverse sequence, and is separated by the splitter 3. The reflected light on one side is converged on an cylindrical lens 9, and the plane shaking of the disk 6 is detected by the optical detector 8. Since a rotary mechanism 10 rotates a lens 7 corresponding to a detected quantity of plane shaking, the light transmitting the lens 7 changes its direction, and the optical axis of the light is made incident on the plane 11 of the disk 6 perpendicularly. Thereby, it is possible to always perform the tracking of the disk 6 stably.
