Wire recorder (Techniek Overig)
Valdemar Poulsen demonstreerde in 1898 al een draadrecorder (de Telegraphone) en was met voorsprong de eerste die magnetische geluidsregistratie toepaste. Het voorwerk was een paar jaar eerder al gedaan door Ernest Rutherford.
Poulsen verkreeg hierop een patent, waarin hij en-passent het principe van de bandrecorder ook nog even vastlegde:
"Instead of a cylinder with a helical steel wire there may be uses as a receiving device a steel band, supported if necessary on an insulating material and brought under the action of an electromagnet. Such an arrangement has the advantage that a steel band of an desired length may be used. Instead of a cylinder there may be used a disk of magnetisable material over which the electromagnet may be conducted spirally; or a sheet or strip of some insulating material such as paper may be cover with a magnetisable metallic dust and may be used as the magnetisable surface. With the aid of such a strip which may be folded, a message received at any place provided with the new apparatus may be sent to another place where it may be repeated by passing the strip through the apparatus at that place."
De praktische uitwerking van deze toepassingen kwam echter pas in de Tweede Wereldoorlog tot stand, hoewel AEG met haar "Magnetophon" rond 1935 al een aardig eind was gevorderd. Rond 1948 kwam de draadrecorder binnen het bereik van de consument, de bandrecorder volgde begin jaren '50.
