Description
Biegsamer Schriftboden für magnetische Aufzeichnung von Phonogrammen. Es ist bekannt, Laute zum Zwecke späterer Wiedergabe mittels Magnet oder Elektromagnet und Telephon oder ähnlicher entsprechender Einrichtung auf elektrolytischem Wege durch Auftragen magnetischen Metalles auf Bänder aus einem diamagnetischen Metall, z. B. Kupfer, festzulegen. Derartige Phonogramme sind in manchen Fällen, z. B. zum Einheften in Aktenstücke, zum Versenden unter Briefumschlag, zu Tonbild-, Grammophonaufnahmen u. dgl. nicht gut verwendbar, weil der Schriftboden aus Metall besteht.Flexible writing base for magnetic recording of phonograms. It is known to use a magnet or electromagnet for later reproduction of sounds and electrolytic telephone or similar equivalent device by applying magnetic metal to strips of a diamagnetic metal, z. B. copper to set. Such phonograms are in some cases, e.g. B. to Filing in files, for mailing under envelopes, for audio and gramophone recordings and the like not usable because the writing base is made of metal.
Demgegenüber besteht die Erfindung in einem Schriftboden aus anderem"sehrbiegsamem Material, wie Papier, Gewebe, Filmmaterial o. dgl., der zur Aufnahme der phonographischen Schrift auf elektrolytischem Wege durch einen dünnen Überzug, z. B. von Metall oder anderen geeigneten Stoffen, vorher elektrisch leitend gemacht worden ist. Unter Einwirkung eines Mikrophonsystems oder einer ähnlichen Tonaufnahmevorrichtung lassen sich in bekannter Weise auf ihm- beim Hindurchbewegen durch den Elektrolyten eine Eisenvitriol-oder Nickellösung, Eisen- bzw. Nickelniederschläge in den Stromschwankungen entsprechend sich ändernder Dichtigkeit erzeugen, die dann in bekannter Weise zur Tonwiedergabe auf magnetischem Wege dienen können. Außer dem Vorzug der vielseitigsten Verwendbarkeit der auf ihm aufgenommenen Phonogramme besitzt dieser Schriftboden dem rein metallischen gegenüber noch den der größeren Billigkeit.In contrast, the invention consists in a writing base made of other "very flexible" materials Material, such as paper, fabric, film material, o Electrolytic writing through a thin coating, e.g. B. of metal or other suitable materials, has been made electrically conductive beforehand. Under Allow the action of a microphone system or similar sound recording device in a known way on it when moving through the electrolyte Iron vitriol or nickel solution, iron or nickel deposits in the current fluctuations produce according to changing tightness, which then in a known manner to Sound reproduction can be used magnetically. Except the virtue of the most versatile This writing base has the usability of the phonograms recorded on it the purely metallic compared to that of the greater cheapness.
