Abstract

PURPOSE:To prevent the reproduction of a picture whose quality is lost by inhibiting the forced frame reproduction when the signal recording mode between adjacent tracks differ. CONSTITUTION:When the recording mode of the signal recorded on an adjacent recording track differs, a signal with a different level is inputted to input terminals 31, 32. As a result, an output D of an exclusive OR gate 1 is always at a high level, an output E of a NAND gate 2 is always at a low level, an output F of a NAND gate 3 is always at a high level and an output G of a NAND gate 4 is always at a high level. At the reproduction of the forced frame, the signal is inputted to an input terminal 28, since the output G of the NAND gate 4 is always at a high level, a head changeover switch 29 selects either of heads 14A, 14B. Thus, only one field signal is reproduced and the reproduction of the picture with bad quality is prevented.
