An Audio Technica AT-F3 moving coil phono cartridge. A magnetic cartridge, more commonly called a phonograph cartridge or phono cartridge or (colloquially) a pickup, is an electromechanical transducer that is used to play phonograph records on a turntable.
Audio-Technica was established in 1962 in Shinjuku, Tokyo, Japan, by Hideo Matsushita as a phonograph cartridge manufacturer. Its first products were the AT-1 and the AT-3 MM stereo phono cartridges. Business rapidly developed, and Audio-Technica expanded into other fields.
Envelope tracking (ET) describes an approach to radio frequency (RF) amplifier design in which the power supply voltage applied to the RF power amplifier is continuously adjusted to ensure that the amplifier is operating at peak efficiency for power required at each instant of transmission.
An example of an electrical force gauge is an "electronic scale". One or more electrical load cells (commonly referred to as "weigh bars") are used to support a vertical or horizontal "live load" and are solid-state potentiometers which have variable internal resistance proportional to the load they are subjected to and deflected by.
A tonearm with the dial for anti-skating adjustment.. Turntable anti-skating is a feature used in phonograph turntables to prevent skating of the tonearm.. Due to the offset between the cartridge's axis (which is approximately tangential to the disc) and the tonearm's pivot, the force applied (through friction) by the rotating disc to the cartridge tends to draw the tonearm toward the center ...
The disc phonograph record was the dominant commercial audio distribution format throughout most of the 20th century, and phonographs became the first example of home audio that people owned and used at their residences. [5] In the 1960s, the use of 8-track cartridges and cassette tapes were introduced as alternatives.

In 1969, a group of University researchers from California founded Pulsar Instruments Inc. which became the first company to display sound exposure times on the scale of a sound level meter, as well as the sound level. This was to comply with the 1969 Walsh-Healey Act, which demanded that the noise in US workplaces should be controlled. [6]
