The cartridge contains a removable or permanently mounted stylus, the tip - usually a gemstone, such as diamond or sapphire - of which makes physical contact with the record's groove. In popular usage and in disc jockey jargon, the stylus, and sometimes the entire cartridge, is often called the needle. As the stylus tracks the serrated groove ...
Turntablists typically manipulate records on a turntable by moving the record with their hand to cue the stylus to exact points on a record, and by touching or moving the platter or record to stop, slow down, speed up or, spin the record backwards, or moving the turntable platter back and forth (the popular rhythmic "scratching" effect which is ...
William K. Heine presented a paper "A Laser Scanning Phonograph Record Player" to the 57th Audio Engineering Society (AES) convention in May 1977. [1] The paper details a method developed by Heine that employs a single 2.2 mW helium–neon laser for both tracking a record groove and reproducing the stereo audio of a phonograph in real time.
Following the fourth song on side one there is a spoken announcement telling the listener to change the speed from 33 to 78 rpm to play the next band of the disc. To play the last song on the side the listener must pick up the stylus from the record, change the speed, then put the stylus at the start of the fifth and final song on side one.

Record-stacking changers eventually became rarer due to the gradually growing belief that they contributed greatly to record wear and "warping," and were eventually superseded by manual turntables which served as separate parts of component systems or were integrated into compact systems that played one record at a time and were felt by some to ...
A stylus connected to a sound-vibrated diaphragm indented the foil into the groove as the cylinder rotated. The stylus vibration was at a right angle to the recording surface, so the depth of the indentation varied with the audio-frequency changes in air pressure that carried the sound. This arrangement is known as vertical or hill-and-dale ...
It supplied turntables and autochangers to many of the world’s record player manufacturers, eventually gaining 87% of the market. The company also manufactured their own brand of player, the Monarch automatic record changer, which could select and play 7", 10" and 12" records at 16, 33 1 ⁄ 3 , 45 or 78 rpm, automatically intermixing ...
