Why don't videotapes last? Even if you
transfer videos to DVD, here's how to best preserve family
video tapes for the future.

Over the past thirty years, most
families have added more and more video cameras and
home movies to their personal archives. Today, camcorders
are super-small and easy to use. Thanks to these devices,
we have become the most recorded human beings ever!
We have videos of weddings, birthdays, parties, grandparents,
children, and more. Future generations will inherit
amazing records of their ancestors, and will be able
to see and hear their great-great grandparents in
vivid clarity.
Or will they? The vast majority
of family videos are currently stored on videotape.
It wasn't until recently that newer formats such as
MiniDVD and hard drives changed the basic videotape
format of camcorders. (And those formats have their
issues too.) If we want to truly preserve our home
videotapes for our children and grandchildren, it's
essential to understand a bit about videotapes. |
FACT: VIDEOTAPES DON'T LAST FOREVER. HERE'S WHY. |
It's not an exaggeration: Videotapes
really do degrade much faster than most people realize.
In as little as 8–10 years, tapes can suffer
deterioration, and total life expectancy is less
than 20 years. A tape frequently shows a lower quality
of picture crispness just after 5 years.
So why does videotape deterioration happen? The
tape in a videotape is comprised of three main parts:
physical plastic tape; magnetic particles (iron oxide),
which contain the video and audio; and the "binder," which
is glue that holds the magnetic particles to the
plastic tape. The particles act like tiny bar magnets
and are changed into patterns when the tape passes
over an electromagnet during the recording process.
When the tape is played back, the patterns are picked
up by a playback head and become the video image.
Over time, the binder glue weakens. When this happens,
the magnetic particles lose their adhesion to the
tape.
Why does this happen to the binder? First, some of the tape is rubbed off every time it is played. This simply happens from the wearing, mechanical nature of VCRs and camcorders, all of which have moving parts that thread the tape over playback heads.
The environment also plays an important role. If
you store your tapes in high humidity, or in a room
where the temperature changes substantially (such
as a spare room that might be warm in summer and
colder in the winter), that dramatically affect tapes.
Plus, magnetic fields in the environment can also
cause signal loss, even when the tape is just being
stored. Furthermore, tapes are vulnerable to sudden
data loss resulting from static shock or strong electric
fields, such as those generated by TVs and other
electronics.
Even worse, the magnetic particles can become separated
from the binder just over time, a process that accelerates
as the tape gets older. This happens because as the
binder absorbs more and more water from normal humidity,
it swells and exposes more surface area – absorbing
even more moisture.
Signs of a weakening binder can first include faded
color and audio changes. Later, the timing and color
signals that the tape outputs to the VCR also start
to fade. Straight lines begin to look a little wavy,
rolling lines can appear on the video, and the picture
can start to jitter because your VCR has trouble
picking up the necessary signals.
A tape is in an advanced state of degradation when
it clogs the playback heads of a VCR or camcorder.
Eventually, the tape can become unwatchable and the
video will be completely gone. When this happens, the
magnetic particles have finally completely broken free
and ended up on the bottom of the tape case.
Thus, the vulnerability of videotapes make them the
most unsuitable media for long-term storage of precious
video memories. |
TIPS FOR STORING VIDEOTAPES SUCCESSFULLY |
But you're not fighting a losing
battle. Proper tape maintenance can slow the deterioration
process and preserve family video as long as possible.
And even if you transfer videos to DVD, always, always, always keep
your original tapes! Never get rid of your master
copies because they will always be the best version.
And this way, you have the option of transferring
your tapes to an even-better format in the future
if possible.
Here are some tips for maximizing the lifespan of your family videotapes:
– Avoid storing tapes in the following
places:
– Concrete
floors: Susceptible to water and high humidity
– Attics: High
temperatures
– Cellars/basements: High
humidity
– Near
bathrooms or laundry rooms: Humidity from steam
– Next
to electronics in a cabinet: High temperatures and magnetism
– Store your tapes
in a stable, cool, and dry environment. Heat
and humidity are the two greatest threats to videotapes.
The reason for this is because magnetic tape expands
and contracts as weather conditions change. This
changes the tape's physical dimensions, which can
confuse a VCR or camcorder. (Do not go cooler
than 45 degrees Fahrenheit though.)
– Avoid rapid changes in temperatures. Do
not use tapes, VCRs, or camcorders if they have been
in high or low temperatures or in humidity. Let them
sit in room temperature for awhile before using them.
Temperature changes and humidity can clog video playback
heads and jam tapes.
– Keep tapes out of sunlight and away from magnetic fields.
– Store tapes in their cases. This prevents dust and dirt from entering the tape cassette, which can increase the amount of magnetic particles rubbed off during playback and exacerbate magnetic charges.
– Store tapes in an upright position, like a book on a shelf. This helps prevent damage to the edge of the tape. Never stack tapes one on top of the other.
– Watch important tapes as little as
possible to prevent wear and tear on the
tapes. Transfer tapes you want to watch over and
over to DVD, then watch the DVD instead and carefully
store the original tape.
– Break the tape's write-protect mechanism. Doing
this prevents the tape from being recorded over accidentally.
To do this, use a small regular screwdriver to break
off the small square tab that can be found on the tape's
spine (the opposite side from the tape mechanism).
– Maintain your VCR and camcorder as
well as possible. Use head cleaners to eliminate
the dirt that can cause abrasive conditions for tapes.
Cover machines and store camcorders in cases to prevent
dust.
– Never touch a cassette's plastic tape
with your fingers.
– Don't splice and reuse broken tapes. Splicing can damage a VCR's heads.
– Don't clean tapes contaminated with
adhesives, fungus, or other substances yourself. Leave
repair work like this to the professionals.
– Transfer your tapes to DVD so the content is safely backed up!

TRANSFER VIDEOS TO DVD. IS THAT REALLY THE BEST METHOD? |
DVD is currently the most practical
and affordable medium to use for transferring videotapes.
DVDs are durable, easy to play, have wide
marketplace acceptance, and provide excellent capacity
for high-quality video. Top-grade DVD discs (such
as those used by Timeless DVD) are expected to last
about 100 years. Lower-quality consumer-grade discs,
such as those sold at office-supply and electronics
stores, are a bit lower at 20-30 years.
DVDs can be played over and over without any loss
of quality. This is because there are no moving
parts on a DVD player, unlike a VCR. A laser reads
the DVD as it spins, and no part of the DVD player
ever touches the disc. So there is no wear and tear.
Although a videotape can be destroyed by a static
shock or magnetism in the environment, a DVD avoids
this problem because the data surface of a DVD
is optical, not magnetic. The data on a DVD disc consists
of an optical layer protected by a polycarbonate protective
surface – which is the same material used in
bulletproof glass! A DVD can even experience light
scratches on this surface and survive intact.
DVDs can be copied with no quality loss.
So it's easy to make backups if you only have one disc
and want additional backup copies. This is not possible
with videotapes, which suffer "dubbing loss" whenever
they are copied to a second tape. DVDs
store video in a digital format, like files on a computer,
which is why they can be copied perfectly.
And finally, wide marketplace acceptance means that
you'll be able to watch your DVDs for many years. While
new technologies are always on the horizon, DVDs have
permeated the market in such a way that machines are
available in almost every household and will be available
to buy for many years to come.
For these reasons and more, DVDs are currently the
most reliable format for long-term storage. However,
we're often asked about other current formats, such
as MiniDV tape, high-definition DVDs, and hard drives.
All of these are excellent mediums, but they do have
drawbacks from the preservation perspective.
– MiniDV: It is still a videotape,
with all the same drawbacks as VHS. In fact, the tiny
width of its plastic tape, the less-durable metal
evaporated technology used by the format, and the
delicate nature of MiniDV camcorders create a perfect
storm of potential problems. That said, MiniDV provides
excellent quality for a transfer and is particularly
good at preserving video for short-term use, such as
footage you may want to edit on your computer.
– High-definition DVD, such as Blu-Ray: In
early 2008, Blu-Ray triumphed over competitor HD-DVD.
But while DVDs for both formats are available, few
consumers have a player, and only time will tell if
high-def DVD will be accepted by the masses or just
used by video enthusiasts. In any case, camcorder video
that's transferred to a high-def DVD will not look
better than that of a regular DVD transfer. This is
because your camcorder video is still analog. Whether
the video is transferred to DVD or Blu-Ray, it will
still only look as good as the original tape.
A regular DVD already preserves 99% of the original
quality from your tape, and high-def cannot improve
on that. The only advantage is that when/if Blu-Ray
discs are more widely used, they will provide more
data space than a regular DVD.
– Hard drives: Hard drives
can be used to store video. But the big drawback here
is failure rate. Say you have all your home video on
a hard drive, be it a computer hard drive or a DVR.
If that hard drive dies, all your video is gone. ALL
of it. Poof! Hard drives may be convenient, the possibility
of failure is a major problem. Alternatively,
if you have your video on a few DVDs, and those DVDs
have backup copies as well, you're in pretty good shape
even if one breaks.
Of course, technology marches on and it's inevitable
that another format will come along to replace DVDs.
That's the way of the world. If you want to preserve
your video in the best way possible, we advise that
you preserve family video onto DVDs, make backup copies
of the DVDs, store your original videotape correctly,
and transfer additional copies onto MiniDV and hard
drives if desired. The more backup sources you have,
the better chances will be that your video will last
a lifetime and beyond.
