AB - MR. D. W. ALDOUS, technical secretary of the British Sound Recording Association (BCM/BSRA, London, W.C.1), has written directing attention to the fact that the use of an iron powder film for the magnetic recording of sound (see Nature, January 19, p. 71) was known some years before the War. This technique was used in the magnetophone developed by the Allgemeine Elektricitäts-Gesellschaft, and it was described by Prof. Erwin Meyer, of Berlin, in a course of lectures given in 1937 under the auspices of the University of London ; these lectures were afterwards published in a book entitled “Electro-Acoustics” (G. Bell and Sons, Ltd., 1939). Apart from the improved technical quality, the chief advantage of the method is the comparative cheapness of the tape recording-medium. Another German firm has developed a pressing process for embossed ribbon recordings, which has useful possibilities for the multiplication of records. It is also understood that British and American workers are active in the field of magnetic sound recording, and that new designs of wire and tape recorders, having applications for commercial and domestic use, may be expected in the future.
