Abstract

1,209,546. Recording and playback. W. E. POSADAS. 11 Nov., 1968, No. 53221/68. Heading G5R. A strip is composed of two layers of materials having different physical (e.g. magnetic) properties, the interface between the two layers forming a hill-and-dale recording which may be read by external means responsive to the different physical properties of the two layers. As shown, two strips 1 of plastics material, each carrying an independent hill-and dale recording, are arranged face-to-face with the varying space between them filled with a ferromagnetic material 2. Flux from a magnet 3 passes through the ferromagnetic material 2 and the nearer recording is played back by means of a head comprising a core 5 with a projecting point 4 and a winding 6. Two heads may use a common core 5. The ends of the composite strip are joined to form a M÷bius loop so that both recordings may be played back in sequence by the same head. The strip is contained in a cassette (9, Fig. 5).
