Why does the binder weaken? First, some of the
tape is rubbed off every time it is played. This occurs because
VCRs and camcorders have moving parts that thread the tape over
playback heads.
The environment also plays an role. If you store your tapes
in humidity, or in a room where the temperature changes substantially
(like a spare room that is warm in summer and cold in winter),
that dramatically affects tapes. We frequently cannot transfer
video from tapes that have experienced these conditions.
Magnetic fields can also cause signal loss, even when the cassette
tape is being stored. And tapes are vulnerable to sudden data
loss resulting from static shock or strong electric fields, such
as those generated by TVs and electronics.
Even worse, magnetic particles can become separated from the
binder just over time, a process that accelerates as the tape
ages. As the binder absorbs water from normal humidity, it swells
and exposes more surface area – absorbing even more
moisture.
