DVL-Digest 1070 - Postings: Index Invention of tape: Invention of tape: was 16mm film camera and telecine - (2) Invention of tape: - "Perry Mitchell" From: Jon Burkhart I'm rather amused when someone new to video tape complains about a brief tape failure they've experienced after having shot many hours without a problem. Video head design and quality control is so much better now than it was in the early days of tape. For several years momentary dropouts were expected. In some operations they would record black on the new tape stock. Someone would go back and view the tape, count the dropouts and decide whether or not to actually use the tape or reject it. Someone at the 3M company invented the dropout compensator and life got much easier. Invention of tape: was 16mm film camera and telecine - "Perry Mitchell" From: Dave Hawley Just to get my bit in before this thread dies, can anyone confirm or deny the story I heard when I joined the BBC in London, (where I still work after 30 years heaven help me,) that the Ampex 2" video recording system came about as a by-product when they were trying to produce a data recorder for medical use? Apparently when they succeeded, by using the quadruplex head system, someone said "hey guys, this thing's got enough bandwidth to record video!" And the rest is history. True or false? Invention of tape: was 16mm film camera and telecine - "Perry Mitchell" From: Dave Hawley If anyone's interested, have a look at http://www.oldboys.dabsol.co.uk This is a site put together by some of my former colleagues, retired BBC VTR engineers, devoted to the subject of the history of video recording in the BBC. It should bring tears of nostalgia to the eyes of anyone who's worked in this field in broadcast TV anywhere, especially if they've been around since before the days of that new-fangled 1" video tape as I have!
