As an independent producer through GRTV you are probably aware of the Hi-Fi switch on the back of the camcorder and also on the control panels of the editing decks. First, it is important to understand relationship between tape speed and signal quality.
Tape speed is the speed that magnetic tape moves past a head .
A head is tiny electromagnet that can detect and read and write magnetic information stored on tape. Generally speaking, the faster the tape speed, the higher the quality of the signal recorded. Any VCR or camcorder has several heads. When you look in the little window at the tape moving in your VCR or camcorder, most would say that the tape appears to be moving fairly slowly. The regular stereo audio heads in all VCR s are stationary.
