Hi Mike, I know the answer to this one by golly!! Audiotape has 4 tracks
side-by-side. The heads play 2 tracks for side one (the upper) and 3-4 for
side two (the lower) but they are recorded in a linear fashion right to
left and left to right, respectively. Chances are that you're getting
bleed-through from from the lower track when you're trying to play the
upper track - 2 causes: either the play heads are misaligned in your audio
deck (in this case the problem should be prevalent whenever you use your
deck) or the tape is magnetically damaged in some way to cause the
bleed-through. Also, if your unit is a stero unit, you might be able to
compensate by turning one speaker right or left totally off (moving sound
balance dial totally to the left or right) - some old-time audiocassettes
used to use this method to play sides. This phenomenon often occurs on old
tapes and tapes that have been played a lot. Nothing to do but toss them -
no fix. Jim Scholtz.
