An "old record player"?

Former Member

Hello,

 

i was thinking about "Phonograph" or gramophone or we all like to called it "record player" an old record player that almost obsolete that used an old black record disk that is in 70's, i know how it work but converting a sound wave from the crooked surface of the record disk to an amplifier to make sound, but i was thinking can the wave show a video output, i know its a completely different from sound wave, think about it, my suggestion is put multiple amplifier to detect the wave that can make and output of not just sound but video wave (of x and y axis) if that make sense. and is this still possible?

 

most appreciate it, if someone can answer this

  • Short awnser, No it can not, The grove the needle goes threw is literally the sound. When recorded for the first time the sound enter the microphone and goes to a device that literally scratches the master record surface. you can not scratch a video to a surface, it is to much data. When 8-tracks and video cassettes cam along they recorded the sound magnetically which led to storing data to a cassette which you could store some pictures but you needed the large reel to reel computer tapes to store very small amounts of pictures.

    hello Bill,

     

    owh i see, yeah that make sense, that why a cassette is created at 1st place, thank for the answer, most appreciate it, but it would be cool if the old durable the master record disk could do much as compact disk. as you said the master record black disk can do at least little data but cannot do much data as to store video data, but if it were to translate into electronic by scratching the surface, there at least some byte of information, can it? as like floppy disk...?

    no, the mediums are totally different. The record stores a physical score and floppy's disk store magnetically. The amount of sound data being stored is minute no where near a byte while a video is usually the gigabyte size. Plus the phonograph only takes one data line at a time ie the sound wave, while a dvd is scannin many more lines all at the same time to produce a video.
