Abstract
1341243 Pressure transducer playback system LICENTIA PATENT VERWALTUNGS GmbH 22 June 1971 [23 June 1970] 29317/71 Heading G5R In a record playback system in which the output signal is produced in piezo-ceramic pressure transducer 2 in response to the reaction pressure on a sled part 3 of the pick up as this compresses the signal deformations recorded in a track groove 12 of record 1, the record to be played back carries a hill and dale recording of a constant-amplitude, frequency-modulated, broad-band signal with at least a second signal having a frequency below the lowest frequency signal of the board band superimposed on the broad-band signal. The amplitude of the second signal 14-15-14 is selected such that the hills 13 of the broad-band signal are engaged by the sled 3 even when scanning a dale portion 14 of the superimposed signal.
