what exactly is the "Hi-FI" in a Hi-Fi VCR? |
|
|
I have a JVC HR-S3911U S-VHS deck and for a while know I have been trying to
find information about "Hi-FI" without much success. Can someone here please
explain what "Hi-FI" does?

Hi-fi refers to a high quality stereo track which is recorded using the |
helical scan head deeper in the tape than the video. This is much higher
quality than the normal edge track recording as the linear tape speed is
low. |

It refers to a High Fidelity audio track (~20-20KHz) versus a much lower
fidelity linear audio track (~100-8KHz.) Similar audio quality difference
as FM radio and AM radio. |

I'll simply state the benefit instead of trying to explain how it works.
Hi-Fi allows near-CD quality stereo audio on your videotapes regardless of tape
speed. This means that it doesn't matter if the recording was done in SP or
EP, as long as there is a Hi-Fi track, you will get near-CD quality audio on
your VCR.
You can play tapes that have Hi-Fi tracks recorded on them as well as record TV
broadcasts and etc. with Hi-Fi audio on your VCR.
Almost every single prerecorded video tape ever made from almost all home video
labels have released movies on Beta and VHS with Hi-Fi audio tracks since 1983,
when Sony first introduced the Beta hi-fi system for their Betamax format
followed by a competing VHS Hi-Fi system from JVC several months later.
The performance of this system is exactly what the name implies. Hi-Fi allows,
well, high fidelity audio on your video tapes so you can enjoy a high quality
soundtrack that you can run on your stereo set while watching the movie.
Now, it's important to note that not all tapes have a Hi-Fi track. Any tape
that was recorded on a non-Hi-Fi deck or prerecorded releases made prior to
1983 do not have Hi-Fi, so the linear, or conventional, audio track is
employed, which is subject to limited dynamic range and frequency response that
gets worse at slower tape speeds. - Reinhart |
