Introduction Since the discovery of ferroelectricity of barium titanate around 1950, many attempts have been made to utilize the ferroelectricity phenomenon for various purposes. However, a limited number of apparatus using barium titanate has been developed, not including vibrators, photomodulators, condensers, etc. This is due mainly to the troublesome phenomena caused by true charges and insufficient quality of the barium titanate products. The physical properties of barium titanate also have not been investigated thoroughly [ 1 I. Pulvari [ 2 ] and Tiong [3]made unsuccessful attempts to cmstruct recording and reproducing instruments using barium titanate. In 1967, Tanaka [4, 51 proved experimentally the possibility of applying barium titanate to recording reproducing instruments, and clarified theoretically and experimentally some fundamental properties of barium titanate. However, Tanaka failed to construct a practical instrument partly because the properties of barium titanate are not completely understood and partly because recording and reproducing phenomena are considerably complicated. We believe that the study of ferroelectric recording is very useful for constructing new recording and reproducing instruments as well TI - A basic analysis of ferroelectric recording JF - Electrical Engineering in Japan DO - 10.1002/eej.4390940106 DA - 1974-01-01 UR - https://www.deepdyve.com/lp/wiley/a-basic-analysis-of-ferroelectric-recording-2rpfibpeNH SP - 33 EP - 39 VL - 94 IS - 1 DP - DeepDyve ER -
