MAGNETIC RECORDING AND REPRODUCING DEVICE

摘要

PURPOSE:To obtain a stable reproduced image having no noise by interposing an integration circuit between a switching circuit for a playback signal and a control circuit. CONSTITUTION:A signal reproduced by a video head 10 in playback mode is applied to a preamplifier 12a through a rotary transformer 9a and a switching circuit 11, and then switched successively and outputted by a preamplifier switching circuit 13. The integration circuit consisting of a C and an R is interposed between a control signal generating circuit 8a and the switching circuit 11a to remove a high frequency component generated by the switching circuit 11, thereby removing the influence of crosstalk upon other channels.
