Stylus

 

a writing instrument in the form of a pointed rod of bone or metal used in Greek and Roman antiquity and in the Middle Ages. The Greeks and Romans wrote with styli on wooden tablets covered with wax; scratches were made through the wax when writing. Erasures were made with the unpointed end, which was spade-or ball-shaped. The name of the instrument gave rise to the abstract concept of style, which in antiquity came to mean literary style and later acquired a number of other meanings.

stylus

(1) A pen-shaped instrument that absorbs current and is used with the capacitive touchscreens on smartphones and tablets. The correct plural word for stylus is "styli", pronounced "sty-lie;" however, most people say "styluses." See Surface Pen, Apple Pencil, stylus pen and touchscreen.

(2) A pen-shaped instrument that is used to "draw" images or select from menus on resistive touchscreens that react to pressure. See touchscreen.


PDA Styli
A stylus was used on old Palm PDAs, which required pressure on the screen to operate. It was included with every Palm organizer (see PalmPilot).







(3) The needle part of a phonograph cartridge, which typically contains a diamond tip. The stylus rides in the grooves of the phonograph record, picking up the vibrations carved into the vinyl, and is attached to a cantilever arm with a magnet or coils at the other end (see phono cartridge). A wide variety of cartridge styles have been used over the years, and there are a huge number of replacement styli available on the market.

When Needles Were Needles
The steel needles at the top were used in old Victrola 78 record players like the unit underneath. They were later replaced with sapphire tips to last longer. The "needle" name obviously came from the long shape of the first styli. (Top image courtesy of Jerry Raskin's Needle Doctor, www.needledoctor.com)

A Modern Stylus
The stylus on this Grado magnetic phono cartridge is diamond tipped. Vibrating in the vinyl record's groove, the stylus transfers the oscillations to the cantilever and magnets. (Image courtesy of Grado Laboratories, www.gradolabs.com)
