Abstract: An optical disc apparatus comprising: a spindle motor configured to drive a turntable on which an optical disc is loaded to rotate; a first substrate on which a first support member rotatably supporting a rotation shaft of the spindle motor is fixed, and on which a second support member is formed at a position adjacent to the spindle motor; a second substrate; an optical pickup device; and a guide member configured to guide the optical pickup device in a radial direction of the optical disc loaded on the turntable, one end of the guide member being supported by the second support member on the first substrate and fixed to a fixing member on the second substrate, and the other end of the guide member being fixed to the fixing member on the second substrate.

Abstract: An optical disc drive is fitted with a pickup, a non-contacting cooling plate, and a resinous movable spacer. The cooling plate adjacently faces and is fixed to the under, right, or left side of the pickup. The movable spacer is fitted to one of the facing sides of the pickup and cooling plate and prevents direct contact between the pickup and the plate. This drive structure prevents pickup movement interference due to collision between the pickup and the cooling plate, contamination production, needless electric conduction, etc., so that the clearance between the facing sides of the metallic pickup and metallic non-contacting cooling plate is narrow. The narrow clearance results in an improved heat conduction and radiation characteristic, improving the cooling of the whole pickup.

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.
