Technical Challenges for the Development of a New Small-Format DVTR

John P. Watney

Starting with today's television tape-recording requirements, this article examines the requirements for a single general-application, small digital format suitable for both ENG and most post-production applications. The technical challenges involved in reducing the required data rate and increasing the volumetric packing density are discussed. Considering tape thickness, track pitch, wavelength, and data compression, it may be concluded that at least three years may elapse before a viable ½-in. standardization effort for television applications could begin. A more desirable 8mm format would take longer. Considering the standardization cycle and the long lead time for the significant very large scale integration (VLSI) production and the development of a full range of products that would be required, the implication is that it will be five to seven 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.
