<p>A recording and play-back system of information which uses a flexible magnetic disc, and produces broadband signals continuously over a long period, without excessive wear on the recording surface of the disc or of the recording head. The voltage and the stability is maintained although the disc is flexible and spring loaded. The instrument consists of a main body (12) with a fixed or smooth surface (11). The flexible disc (12) will rotate on this surface. The storage medium contains a central assembly section (14) and an external section (15) for the recording. The recording medium is disc shaped and the surface is coated with a layer which reacts to a magnetic flux. The rotation of the disc will activate a liquid cushion between the lower surface and the cylindrical top surface.</p> |
