Abstract

1322295 Producing copy tapes MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 19 April 1971 [18 Feb 1970 24 Feb 1970] 21941/71 Heading G5R In a method for producing slave copy tapes 11 from a master tape 1 bearing audio signals 3a/3b and control signals 4a/4b, the audio signals are reproduced and then directly rerecorded using heads/amplifiers 5, 6, 8, 10, but the control signals, after passing through devices 12-19, are instead used to operate a relay/ switch 20/21 to allow an oscillator 22 to record fresh, accurate, control signals on the slave tape. Alternative single and double track embodiments wherein selective signal filters are used are described with reference to Figs. 3-5 (not shown). (For Figure see next column.)
