For research i am looking at the many existing methods that we use for storing information. This post is about explaining as simply as possible how a record works so here goes... Sound is made of waves, these waves are cut into records as grooves. Based on the amplitude and frequency, the groove changes. A needle runs in this groove and transfers the vibrations to a diaphragm. From here a preamp picks up the sound and amplifies it to a level that is reasonable for the stereo to reproduce. The stereo amplifies this signal to whatever volume your choose.
