	A little bit over a week ago I asked the net a question about
	why one can weakly hear a song before it starts on a record. In
	response I got two main answers, both of which I had suspected
	in the first place. One of these reasons is print through on the
	master tape, ie. where the magnetic information on a piece of
	tape rearranges the patterns on the next layer of tape on the
	reel. The other reason cited was called groove echo, in which
	the cutting tool deforms the master disk, and thus pushes the
	modulations over into grooves wich have alredy been cut.
	Responses varied from one end to the other, some stating that
	the problem was due entirely to print through ,and others saying
	that it was entirely groove echo. Then there were some responses
	saying that it could be one or the other depending on
	circumstances, which to me seems to be the most reasonable,
	although I still wonder which is the more prevalent cause.

	Thanks to all who replied.
