VHS tape playback: S-Video + S-VHS heads vs. Composite & VHS-optimized heads

    For best VHS tape playback quality for digitization / archival
    purposes, is it truly better to use a S-VHS VCR for reasons of S-Video
    connectivity and perhaps better overall design, than say a high
    quality VHS deck (not what they make today, but one of the higher end
    older machines which did not have much wear and tear).

    The reason for my doubt is video head design - on the VHS, the
    multiple head sets would be optimized for VHS SP and VHS EP (or LP)
    playback.

    On a S-VHS deck, would there be separate heads for VHS, or would S-VHS
    heads be used for VHS mode playback? If so, are there any tradeoffs
    sacrificing quality as far as VHS signal retrieval is concerned?

    Thanks

    P.S. The VHS tapes would be PAL, and a S-VHS VCR I am considering
    would be Panasonic NV-FS88 or NV-FS90 or NV-FS100 or NV-FS200 (not
    sure which is the best one).

    If you really have a good, old VHS machine it *might* be better
    than a current S-VHS machine. But you'd have to do the acctual
    experiment to know for sure.
    I don't know of any generally-available VHS decks that have multiple
    sets of heads for LP/EP/LP or for VHS/S-VHS.

    For best VHS tape playback quality for digitization / archival
    SVHS machines do not have separate video heads for SVHS and VHS. That is
    unnecessary, since the difference between the two signal formats is in the
    video FM signal bandwidth.

    A well-designed, properly adjusted SVHS machine will play VHS tapes better than
    a poorly designed, poorly adjusted VHS machine. That it is a an SVHS machine
    does not, by itself say anything whatever about how well it plays VHS tapes.
    The original selling price is a much better predictor of performance (you get
    what you pay for). That understood....

    You want a machine with separate (pairs of) video heads for:

    1. SP (38 microns or wider)
    2. EP/SLP/LP (19 microns)
    3. VHS-HiFi (~6 microns IIRC)
    4. Flying Erase Head (1)

    You also want a built-in TBC (time-base corrector) and dynamic tracking...but
    you probably can't afford the latter.

    Now, what can you afford?
