Recordings from the Recorder as of 11-2011
"The old magnetic-tape records preceded the eight-track, the cassette, the CD, and the latest recording and storage media (like mp3) for analog or digital information...Why, my parents depended on "the Recorder" to keep in touch during his deployment; and I remember listening to a few of his recordings to us, his children - as it was..."
"Recordings from the Recorder" dates-back to the days of reel-to-reel recorders such as illustrated to the right. The units that my parents had was a matching set (one gray and one red) that he may have purchased in Japan or overseas.
The magnetic
tape used on the real for recording was brown in color: a simple
explanation of the technology was that the magnetic tape is encoded in
proportion to audio signals discharged from the tape recorder (head); as to how
the who process works, or audio is recorded from voice to analogy signals,
please refer to Wikipedia or some other source - or call my brother who is an
electrical engineer (although he might charge a consulting
fee). 
When I was in college, my senior project involved a local operation that manufactured magnetic tape: a company by the name of AMPEX, my brief search on tape recorders indicated that the company began in the 1940's with financing from the famous actor, Bing Crosby, and the genius of the developer, Jack Mullin, who had been in the army in WWII. His mission in the Signal Corps (a unit specializing in electronics) enabled him to acquire some German-made hardware that was the first of this technology. With this base and financial backing, he began the company that eventually led to stereo, video and computer data recording using magnetic tape. Surprisingly, this analog-medium is still used in the present day because, according to my source, it offers a more natural or mellow sound recording than digital.
As the user of some later forms such as cassette and VHS recorders, the problems could include stretching and eventual tearing of the tape; the most common experience, was having your tape player "eat" a tape - which meant almost certain loss of the tape (music or movie) and possibly, lingering problems with the tape player. All that said, this magnetic tape was still a vast improvement over earlier media (vinyl records) and was much more mobile and convenient; enabling you to carry your tunes on a trip in the car or on foot.
