Similar units were widely used for recording and broadcasting in the 1940s and are occasionally still used today. Sound recording began as a purely mechanical process. Except for a few crude telephone-based recording devices with no means of amplification, such as the telegraphone, [a] it remained so until the 1920s.

1969: The charge-coupled device, the first image sensor used in digital imaging, invented by Willard S. Boyle and George E. Smith at Bell Labs, [7] based on MOS capacitor technology. [8] 1970: James Russell patents the first digital-to-optical recording and playback system, [9] which would later lead to the Compact Disc.
Wire recording, also known as magnetic wire recording, was the first magnetic recording technology, an analog type of audio storage. It recorded sound signals on a thin steel wire using varying levels of magnetization. [1][2] The first crude magnetic recorder was invented in 1898 by Valdemar Poulsen. The first magnetic recorder to be made ...
