Claims (1)

[Scope of utility model registration request] a plurality of rotary heads that sequentially reproduce recording media in synchronization with a head switching signal; a dropout detection circuit that detects a dropout in the reproduction signal of each of the heads and outputs a dropout detection pulse having a pulse width of the dropout period; Partially demodulated signals obtained by demodulating the reproduced signal of each head are input to different input terminals, and continuous demodulation is performed in which the partial demodulated signals are connected by switching control based on the switching signal when the detection pulse is not output. a switch means that outputs a signal and stops the signal output by switching control based on the detection pulse when the detection pulse is output; a capacitor that is charged and discharged by the output signal of the switch means; and a discharge time constant for the capacitor. A playback device comprising a loss compensation/shut circuit having a parallel circuit of resistors.
