i have created a small device which i wish to use. the device consists of a rotating drum covered with VHS magnetic tape , and 2 tape heads from an old radio , which i know work.
i would like to write and audio signal with one of the heads and read it again simultaneously with the other head while the drum is rotating. this is to see what kinds of distortion magnetic tape creates.
one of the heads has a resistance of 200 ohms and the other head has a resistance of 4 ohms.
i believe that i am missing something crucial. tried several signals on the "input" but got nothing out of amplifier circuits on the outputs.
Help? i know some of you veterans know tape like the palm of your hands.
