登録請求の範囲第１項記載の磁気記録再生装置。[Claims for Utility Model Registration] 1. In a VTR that records and reproduces one field of a television signal on a magnetic tape in one track, pseudo vertical synchronization is performed during a period other than the vertical blanking period of the television signal for recording. means for adding a signal, means for extracting the pseudo vertical synchronization signal from a signal reproduced after recording the television signal and regenerating a regular vertical synchronization signal, and mixing the generated vertical synchronization signal into the reproduction signal. magnetic recording, characterized in that the vertical synchronization signal generated from the pseudo vertical synchronization signal is added to the reproduced television signal when the regular vertical synchronization signal is not reproduced. playback device. 2. In the magnetic recording and reproducing device, when recording is performed by adding a pseudo vertical synchronization signal to a phase delayed by about 1/2 field from the regular vertical synchronization signal, and when playing with tape running stopped, pseudo vertical synchronization is performed. The magnetic recording and reproducing apparatus according to claim 1, wherein the tape running is controlled so that the reproduced RF signal of the signal section is maximized.
