<description>The following document is a term paper describing embossed disc technology.  Although the paper primarily focuses on the embossing process with regard to uncoated aluminum discs, other commonly used embossed discs are also briefly covered.  This paper begins with the early history of recorded sound (Edison, 1877) and follows the embossing practice of discs through its life cycle</description>

<paragraph>The concept of embossing a groove along an adaptable material was the very first in recorded sound. <proper name>Edison's</proper name> original recorded sound invention in <historical date>1877</historical date>, the "<keyword>phonograph</keyword>," embossed a groove into tinfoil by the vibration of a recording point. <proper name>Edison</proper name> was quickly caught up to, in <historical date>1887</historical date>, by <proper name>Charles Sumner Tainter</proper name> & <proper name>Chichester Bell</proper name>, who together developed <proper name>Edison's</proper name> idea further into the             "<keyword>graphophone</keyword>," and engraved sound's modulations into wax, in place of <proper name>Edison's</proper name> embossment of foil. This advancement allowed for commercial development since the cylinders could be played more than the precious few times that <proper name>Edison's</proper name> tin foil phonograph made possible. The issue of embossment versus engraving became the central argument in the licensing wars that ensued between the phonograph and graphophone inventors. Embossment in the recording process disappeared for several years, persisting only in zinc disc recording, until the arrival of instantaneous recordings, when it was employed steadily for nearly two decades.

            <paragraph>The primary discs that were recorded by an embossing process were uncoated aluminum discs, which will be the focus of my paper. However, there were several other commonly used          embossed discs and I will briefly cover these as well.
