|Drop out can be caused
by imperfections in the oxide layer of the tape or
dust particles momentarily lifting the tape away from the record head.
It is recommended that new
tape be fast forward to the end and then rewound
before use. The notion here is that any loose particles on the tape
will drop off during this exercise.
|Drop out can also be the result
of careless handling of recording tape. Oil
from fingers and hands can adhere to the surface of
tape and attract dust and other contaminants resulting in a barrier between
the oxide layer and the playback head.
