Technical Challenges of a New Small-Format DVTR

Starting with today's television tape recording requirements this paper goes on to examine the requirements for a single general application small digital format which might serve both ENG and most post production applications. The technical challenges involved in both reducing the required data rate and increasing the volumetric packing density are discussed. Considering tape thickness, track pitch, wavelength and data compression, it is concluded that it would be at least three years before a viable half inch standardization effort for television applications could commence. A more desirable 8mm format would take longer. Considering the standardization cycle, the long lead time for the significant VLSI production and the development of a full range of products that would be required, the implication is that it will be 5 to 7 years or more before a viable, standard, general purpose small format television DVTR could be available in product form. Military reconnaissance applications which are less demanding than television applications in the areas of play time and multigeneration capability could be met with the best of existing technology.
