MAGNETIC RECORDING AND REPRODUCING DEVICE

摘要

PURPOSE:To obtain a wide frequency band by using an inter-channel crosstalk cancelling means to reduce the inter-channel crosstalks more effectively. CONSTITUTION:A crosstalk cancelling winding part 7a' led from a winding 7b wired to winding 7a and a series and a crosstalk canceling winding part 7b' led from the winding 7a wired to a winding 7b and a series are buried into cut parts formed to the cores existing between grooves 5a and 5b respectively. The part 7a' is set such a number of turns that produces the induced elelctric power having the same level as and an adverse phase to the crosstalk amount given from the winding 7b. While the part 7b' is set such a number of turns that produces the same level as and adverse phase to the crosstalk amount given from the winding 7a. A short ring is provided to a rotary transformer together with a crosstalk canceling transformer 10. As a result, the crosstalk can be reduced more effectively.
