[BC] Cassette deck maintenance

[Tom Dimeo]

I got to thinking about this maintenance question and came up 
with this idea.  The answer is to have a cassette loaded with 
white tape.  The tape can be marked with, let's say, a red 
line at 1.75 inches, a green line at 3.5 inches, a blue line 
at 5.25 inches, a yellow line at 7.0 inches and a black line 
at 8.75 inches and the process could be repeated for thirty 
or forty-five minutes.  Then all you need is a good stopwatch 
and a good eye.

Perhaps I've been spending too much time in the classroom of 
Mr. Osenkowsky?
