Abstract
A positioning apparatus has a guidance system including first and second bearing means in which a pressure on one side of a guide plate and a height adjustment on its other side to be positioned are sufficient to provide an unambiguous controlled guidance virtually without deviation from the axis of movement of the guide plate. An advantageous construction is provided by a rotary bearing arrangement substantially in the form of an isosceles triangle. A particular mounting pivot point on the bearing support simplifies the assembly of an apparatus having a band drive means. The apparatus is suitable for all types of information recording and playback apparatuses employing disks or disk-shaped media, and also for positioning purposes in robots, etc.
