Phonograph Needle

a component of the tone arm that picks up mechanical vibrations as it moves along the grooves of a record. Phonograph needles are usually cylindrical, narrowing into a cone. The cone ends in a hemisphere, which is the working part of the needle. A distinction is made between fixed needles, which cannot be removed from their holder, and replaceable needles, which are fastened by a screw to the diaphragm in old-style sound pickups. Fixed needles are made from corundum or diamond. Corundum needles last about 150 hours; diamond needles last ten times longer. Replaceable steel needles with a service life of about five minutes were used to reproduce recordings from 78-rpm phonograph records.

Just ask by Sunday Mail (Glasgow, Scotland) Whether or not the devices actually did what they were said to do, the installation owed less to its sensuous realization than to its idea, which recalled a rich history of oddball phonographic experiments, among them Thomas Alva Edison's crackpot attempts to communicate with the dead and Rainer Maria Rilke's proposal to use a phonograph needle to play the human skull.
