Needle playing a record. Colored scanning electron micrograph (SEM) of the needle (stylus) of a record player in a groove on a record. A record is used to store sound. It is produced by a machine with a head which vibrates in time to the sound being recorded. This cuts a groove in the record which varies according to the vibrations. A needle can then reproduce these vibrations as it runs along the groove and these, when amplified, produce the original sound.  This is a stereo record.  The needle in contact with the record is a LP needle, or a long play needle designed for stero use.   This record is designed for 45 RPM.  Magnification is 100x when printed at 10 cm wide.
