ABSTRACT:
A rack drive contains a suspension tooth element which is formed by a rack which has a guide opening parallel to its row of teeth. The rack opening is guided on a bearing bolt of the drive pinion for the rack. The suspension tooth element is preferably connected via a drive pin to a device which can be variably positioned and is produced integrally from an acetyl polymer. The rack drive can advantageously be used as a positioning device for controlling a scanning and/or recording device in a recording and/or playback unit for optical recording media but is not limited to such.
