Abstract

The invention relates to a scanning device for optical storage media, having an optical housing with sliding bearings, which are arranged at a distance from one another, for linear movement on a guide rod, and with optical components in order to form an optical path. It achieves the object of designing a scanning device such as this in such a way that its adjustment, associated with a setting of the optical path, is simplified and can be carried out precisely. For this purpose, each of the sliding bearings is formed from a sliding bearing bush which is held on a guide block, that is fixed to the housing, in such a way that it can be adjusted in a radial direction with respect to this guide block, and is self-aligning in a direction at right angles to this.
