Techniques for production are being established and uniformity of output will be assured through the thousands of feet being produced for developmental purposes. Trends in Recorder Design. — Few recorders designed to use coated tapes have been built in this country. Most of these have been engineered to meet the requirements of the home recording enthusiast, and none, so far as the writer knows, has reached the market. One model now being planned will have a frequency range of from 50 to 9000 cps, and will be suitable for commercial recording. During FIG. 7. Simplified magnetic tape recorder mechanism. the coming year, there will no doubt be a number of commercial high-fidelity tape recorders produced. Most of present day experimental tape recorders use 8-mm film reels with the 1/4-in. coated ribbon. Fig. 7 is a simplified version of a mechanism suitable for use in coated tape sound recorders.
