Abstract
PURPOSE:To delete the light emitting part for detecting a position by providing a reflecting mirror to reflect a part of a laser light for the writing or reading of the information on an optical medium and make incident through a position scale fixed to the base of an optical disk device onto a light-receiving element for detecting the position. CONSTITUTION:A laser light 23 bent in a right-angled direction by a reflecting mirror 9 in the direction of travel passes through a hole 13 provided at a head case 21, passes through a pattern written on a position scale 12 fixed in parallel to an optical head moving direction to an optical disk device, and thereafter, the light in made incident on a light-receiving element 14 provided at a light- receiving part 11. Thus, when the optical head 20 is moved by a driving means, the incident place for the position scale 12 of the laser light 23 is moved and thus, the incident light to the light-receiving element 14 is changed. Here, the output in accordance with the fluctuation of the pattern can be detected from the light-receiving element 14, the detecting output is used and the position of the optical head 20 can be known.
