Tone Arm

 

a component of the sound pickup that holds the pickup head and makes possible movement of the head from the edge of a phonograph record to its center.

A tone arm is usually a hollow metal rod. The pickup head is mounted on one end of the rod; the other end is equipped with a stalk that is used to rotate the tone arm in the vertical and horizontal planes and a counterweight that is used to adjust the pressure exerted by the pickup on the record groove. A special device ensures the smooth lowering of the pickup head onto the record.

Since their introduction, CDs have been the obvious choice: no endless fussing with tone arms, cartridges, and of course the LPs themselves; and most importantly, CDs did not suffer from the near instantaneous sound degradation that plagued vinyl.
