Abstract
As magnetic recording has developed, many different kinds of heads have been used or proposed. Some are quite different from standard designs and have worthwhile advantages. Why weren’t they used more widely? Some were forgotten and some never publicized. Some required materials or techniques that weren’t available. Some didn’t have enough advantages; some had advantages that weren’t needed and some were too costly. Recent concepts are still under development, with problems yet unsolved. However, all of these are useful in stimulating thoughts for new designs or unusual applications.
