Linear motion for moving a recording or playback head is provided by a rack-and-pinion mechanism. The rack Ä2Ü, produced from low friction plastic material, has a long slot with the teeth formed on the inner surface. In mesh with the teeth of the rack, a pinion wheel Ä3Ü connects to the drive motor via a reduction gear train. The end or the rack carriage is mechanically coupled Ä5Ü to the unit that is to be moved along a linear path. <IMAGE> |
