Maybe. ISTR that wehn CE's were working on the CDC STAR station drums,
they routinely rewrote timing tracks. I recall that their only tools
were a scope and a Halliburton CE box. Apparently, the goal was write a
track such that there was no detectable "splice" in the beginning/end of
the track. Pretty much a cut-and-try operation.
Perhaps the LGP30 is similar.
