What does DVD mean?

"Digital Versatile Disc"

What does CD mean?

" Compact Disc"

How does DVD technology differ from CD?

Like CDs, DVDs store data in microscopic grooves running in a spiral around the disc. All DVD drive types use laser beams to scan these grooves: Minuscule reflective bumps (called lands) and nonreflective holes (called pits) aligned along the grooves represent the zeros and ones of digital information.

But that's where the similarities end. DVDs use smaller tracks (0.74 microns wide, compared to 1.6 microns on CDs) as well as new modulation and error correction methods. These technologies allow them to store data seven times as large as that of a CD.

Will DVD discs wear out, like VHS movies?

No. The picture quality of the DVD disc is consistent from the first play to the thousandth play. Plus, DVD discs will not deteriorate over time, are unaffected by magnetic fields (which can literally erase a VHS cassette) and do not require rewinding after viewing.

One more advantage of a DVD disc is that it is not physically touched while it spins in the player, so there is no wear and tear or loss of fidelity over time. In contrast, videotapes do touch a playback mechanism and can eventually break down, degrading the quality of picture.

Will KEEPEMFOREVER discs play in my DVD Player or Computer?

Most newer DVD players that recognize CD-Rs and DVD-Rs will work fine.

Almost all computers with DVD drives and the right program will work.

CD-roms should play KEEPEMFOREVER CDís with DVD programs.





Why I started this Site

About 1980, I bought a video camera to replace my Kodak XL10 Movie Camera. Over the years, I videotaped everything I could, my kids, plays, ball games, magic shows, vacations, etc. If I could go to an event, I would try to take my video camera.

Well, I soon collected many videotapes, bought several cabinets to keep them in, I tried my best to take care of these masterpieces of compulsion. I have collected over 1000 VHS tapes.

I would not let these memories get too far out of my site, for fear of damage, I had heard of tape players eating tapes, and that was reason enough not to share and not to watch them too many times. I wanted to keep these memories for the future. I had invested time and money and didn't want to lose any more.

Well, the future is here and I was about to lose my time, my money, and my memories. I had discovered that some of my tapes were not as sharp as they once were. What is going on!

I discovered the shelf life of VHS tapes and other magnetic media was NOT FOREVER or not as long as my life, or half as long.

Noticeable degradation in about 10 years, after 20 years there will be problems even under ideal conditions, if you can't see any problems, you are lucky. The fact is, VHS tapes were not meant for long term data storage. The binder that holds the magnetic particles on the the tape starts to let go during the wear and tear of normal use, and over time, just lets go.

The particles on the tape will move just setting on the shelf, and if you decide to play the tape, think of all the parts in the player that will be rubbing against it. This alone is the biggest reason for tapes fading away, wiping the data right off the tape.

If outside magnetic interference is not a problem, say you keep your tapes in a steel box, under the best conditions possible, the small magnetic field of the tape itself is degrading the data by constantly trying to neutralize itself.

Oxidation is another culprit, if air can get to it, you will have it. The oxidation will rewrite your data to something else causing a snowy spot here and there.

There are other reasons for degradation of magnetic media, but these are the most common causes.

They really don't know how long DVDs or CDs will last, but one of my suppliers says at least 100 years. Time will tell, testing is still going on.

DVDs and CDs are optical media, and light is all that touches them.

Information is stored in a digital format, VHS is stored in an analog format.

Analog data is stored in shapes of magnetic fields on VHS tape.

Digital data is stored in numbers, ones and zeros and their intensity or values are represented by high and low spots burned into the disc of DVDs and CDs that plot a pattern of the shapes of the analog image. (This is my own interpretation)

I finally figured out what to do, I will put my best videos on CDs or DVDs.

After I had converted a few tapes to CDs, I decided to move up to DVDs. The hardest part of transferring from VHS video to DVDs was the encoding, I have tried many encoders, hardware and software. I try to stay on the bleeding edge of technology in this area.

I figured that somewhere out there, somebody would pay to have this done, after all, not everybody can or will, spend the time and money to do this kind of work, I guess it is a passion with me.


At present I can transfer VHS, VHS-C, Mini DV, and Hi8mm video tapes to CDs or DVDs. This is a wonderful way to share your memories, especially weddings and birthdays.

I can do editing, I can shorten, cut out unwanted scenes, transitions, titles, and add music. THIS DOES COST EXTRA !
