Title: Magnetic recording and reproducing device by depth recording
Inventor: MANABE MAKOTO
IPC: G11B5/02
Filed: 1987-05-14
Abstract: PURPOSE:To improve the S/N of a signal depth-recorded by inserting a filter means to compensate the frequency characteristic of the erasing rate of a sound FM signal by a luminance FM signal to the recording system of the sound FM signal. CONSTITUTION:Right and left sound signals are respectively inputted from input terminals 1 and 2 and given to a first FM modulation circuit VCO3 and a second FM modulation circuit VCO4. The circuit 3, for example, has 1.3MHz as a center frequency and the circuit 4, for example, has 1.7MHz as the center frequency. A BPF7 cancels a higher harmonics component in the output of the circuits 3 and 4 and obtains the frequency characteristic of the level of sound FM signal to be recorded as a desired one. The output of the BPF7 is supplied through a coupling capacitor 10 to a recording amplifier. This BPF7, for example, has 2MHz as the center frequency and by the frequency characteristic of a low area side, an erasing due to a luminance FM signal is compensated.

Title: Field discrimination device
Inventor: MORI YASUYUKI
IPC: H04N5/10
Filed: 1989-05-11
Abstract: PURPOSE:To prevent incoming noise and missing of a horizontal synchronizing pulse by providing a field error detection section correcting an error of a field detection section to output a field discrimination signal. CONSTITUTION:When the inputs to a comparator circuit 3 differs, since a counter 4 is counted up by each field, the output count is incremented by one for each field. When the count reaches a prescribed number N, an inverting circuit 5 is operated to invert the polarity of the flip-flop 2. Thus, the output S of the flip-flop 2 and the output H of the field detection section 11 are the same and the counter 4 is reset, then the outputs H, S have the same polarity. When a correct field discrimination signal is outputted from the flip-flop 2, so long as the field detection section 11 malfunctions for at least N fields or over, a correct field discrimination signal is outputted.
