[comp.unix.wizards] question on effects on computer tape as videotape...

peterli@ucsfmis (Peter Li) (06/27/89)

I know this topic has been posted before, but here is a new twist:

1.  How long does it take to ruin the video head if a computer tape is used 
    in place of the videotape ?
2.  Is the destruction dependent on length of tape or play speed or both ?
3.  What is the nature of destruction, is it reversible ?
4.  How complete is the loss of picture and audio ?
5.  Is the computer tape destructive on linear audio head and erase head ?

I am posting this because I remember there were some discussion of this
type before.  So some of you have tried it and witnessed the result,
and I don't really want to repeat the expensive experiment.

Never, ever try to use a magtape designed for one application in an
entirely different application.  They have many characteristics that
are tailored for the intended use, and using one for an unintended
purpose can damage the equipment (usually due to differences in
lubricant), and at best will have the wrong magnetic properties,
leading to degraded performance.

I don't know precisely how long it would take to ruin your video
recorder; it's not an experiment I would try on mine.
