Abstract

PURPOSE:To continuously reproduce a screen without a noise by scanning a track corresponding to one magnetic head with the magnetic head, reproducing a video signal of one field, and reading out the video signal of one field written in a memory during the period corresponding to the other field. CONSTITUTION:The video signal is continuously reproduced which has a prescribed level difference, frequency-multiplexed with the pilot signal of an ATF system by a pair of magnetic heads with different azimuth angles, and intermittently recorder per frame unit on a tape. In a continuous reproducing (reviewing) mode, since the magnetic tape continuously scans at a standard speed, the scanning locus of magnetic heads HA and HB obliquely intersects the central line of the recording track formed on the stopping magnetic tape. Thus, the reproduced video signal of the other field, where a high-level reproducing RF signal is obtained, is written into the memory, and the video signal read out from the memory is substituted for the reproducing video signal of the other field, where the reproducing RF signal is in the low level, and the continuous reproduced screen without the noise can be obtained.
