Abstract
1298118 Magnetic recording/playback PIONEER ELECTRONIC CORP 13 Aug 1970 [15 Aug 1969] 39099/70 Heading G5R A high frequency oscillator 4 is used during a recording operation to supply both bias current to a magnetic recording head 3 and erase current to an erase head 6, and during a reproducing operation is used to supply control current to a semi-conducting Hall-Effect head 8. The output signal from the head 8 is filtered by a circuit 9 and demodulated by a circuit 10.
