Linear tracking arm assembly with electric brake

摘要

A linear tracking arm assembly for linearly tracking a recording medium in response to manual or automatic lead-in and return indications, which includes a linearly movable conveyer means carrying thereon a pick-up arm. The linearly movable conveyer means is driven by an electro-magnetic linear motor. An electric brake means is provided on the conveyer means, for applying a suitable brake to the electro-magnetic linear motor in accordance with a speed of the conveyer means.
