There is no manufacturer that will guarantee that information will remain on tape indefinitely. VHS is the dominant video duplication format. SVHS and 8mm video make up a relatively small percentage of duplication orders. Consumer Beta formats have virtually disappeared from the market. Most programs do not require hi-fi sound.
Most clients settle for a good quality, mono linear track.
Tape shells are available at very low prices, but they're not meant for many plays. Class B shells played several times will produce high dropouts, possible jamming and tape creasing, and the shells are fragile due to the thin, low-cost plastic used in manufacture. Copy protection is not overly-important to the majority of duplication buyers. In most cases, the benefits don't justify additional price. Standards conversion for overseas distribution is becoming very important.
