Audio is also a consideration, especially when
you VHS convert to DVD. Linear track or normal
audio is standard on all VHS VCRs. The linear track uses stationary
audio heads to record sound with traditional recording techniques.
The process is identical to methods used by audio cassette recorders.
Higher-quality VCRs are also available with Hi-FI sound. As
mentioned above, Hi-Fi requires extra heads that are mounted
on the video head drum assembly. Hi-Fi VCRs produce sterero sound
in excellent quality, particularly when converting
video to DVD. Also note that on VHS machines, Hi-Fi may also
be called high definition audio.
A good VCR is the most essential element to the
playback picture – especially when making a VHS to DVD copy.
If an excellent video picture is important to you, look for a
VCR that contains an internal time-base corrector. An inernal,
or "line" TBC,
cleans a signal and improves the image reproduction. It can also
help stabilize and track the image, but usually not as effectively
as an external TBC.
But beyond that, VCRs that contain TBCs generally also have
better heads and transport mechanisms than cheaper consumer VCRs.
They therefore help in providing a more noise-free and clearer
image, which is very important when transferring tapes
