Due to manufacturing errors, changes in videotape machinery and videotape formats, and not a hell of a lot of experience on anyone's part, there are some immediate, obvious problems that need solving when considering the transfer of early videotapes.
The tapes concerned are the reel to reel tapes made from the late 1960s to about 1975. This includes several formats of 1/2", 1/4", and maybe some 1" videotape. Information on 2" tape needs only to be transferred by commercial services still currently available.
