The Effect of the Choice of Tape Format on Broadcast Video Recording

Design and performance characteristics of various types of video recording devices are compared. The relation between the two bask types (quadruplex and helical) is shown for characteristics such as signal-to-noise ratio as a function of tape speed and magnetic coercivity. It is indicated that equipment cost is more a function of desired performance than of basic type and that the high state of development and standardization of the quadruplex will assure its continued use in TV broadcast service for the foreseeable future.
