Selective reproduction system for audio or visual recording - has index code read from card supplied to search processor

Abstract

Abstract The system, for a required section of a recording, uses index codes associated with each section, inscribed on the recording support, the required section denoted by an index code read from a reference card. The code reader scanning the latter is coupled to a processor controlling the search operation for locating the required section. Pref. the recording support comprises a magnetic tape with two adjacent recording tracks, one used for the audio and/or visual recording and the other used for the index codes. In the case where the recording represents a printed text, the punctuation characters may also be recorded along the second track.
