Title: Sound recording circuit of tape recorder
Inventor: NAGAHAMA KOUJI
IPC: G11B5/027
Filed: 1980-09-11
Abstract: PURPOSE:To record sound always under an optimum state, by holding a reproduced signal at the same time as a recording signal, which is held in the first integral holding circuit, in the second integral holding circuit. CONSTITUTION:The recording signal from a sound recording signal source 6 is not only applied to a recording head 3 but also has a part held in an integral holding circuit 15. This holding time is controlled by an astable multivibrator 24. Meanwhile, the reproduced signal from a reproducing head 4 is held in an integral holding circuit 17. This holding time is controlled by a signal obtained by frequency- dividing 25 the signal from a control circuit 26 but is controlled with a time delay corresponding to the distance between the recording head 3 and the reproducing head 4. Consequently, the reproduced signal at the same time as the held recording signal is held in the holding circuit 17. Signals in both holding circuits are compared 19 with each other, and a variable characteristic amplifier 8 in a sound recording circuit 5 is controlled by the comparison result to perform compensation. Thus, sound is always recorded under an optimum state.
