WIRELESS RECORDS PRESERVED
FOR FUTURU REPRODUCTION. Loudon, May 20. The “Star” reveals a marvellous development in broadcasting, by which speeches and concerts can be preserved and reproduced at will, instead of being lost in the. ether as at present. German experts’, it says, have discovered a method of using a hard steel wire, which, when passing through a nmgnetid field, becomes permanently magnetised by the currents issuing from' the microphone. The wire is then rolled on a spool, and reproduction of the sounds is achieved by running the wire past a magnetised soft iron core, by which the sounds are repeated through a telephone receiver or a radio transmitter. Speech is reproduced faithfully, but music is not yet satisfactory.—Aus.-N.Z. Calle Assn.
[The claim that the use of a steel wire for making a permanent magnetic record of sounds is a new German invention is incorrect. It has been known for several years, and a fullydeveloped apparatus produced by an American company was demonstrated in New Zealand some years ago by an Auckland business man.]
