<p>That seems reasonable to me, but I've never transferred a tape
recorded with HX.</p>
<p>I expect that HX would cause AM modulation of the recorded bias
level, but that's not a problem as long as the bias signal to
noise at the lowest bias level is still adequate.</p>

<div>yes, I was casting about in my head for the
appropriate work to call HX, process seemed most likely.

<div>the point is that, as you point out, it modulates the
bias, which should then change the location of the
trailing edge? What affect does this have on the bias
signal on the tape for John and Jaime to process?</div>
