发明名称 Video tape recorder including vertical recording heads
摘要 A helical scanning type video tape recorder includes a rotary cylinder which is slidable on a video tape; and a pair of vertical magnetization recording heads mounted on the peripheral wall of the rotary cylinder at prescribed positions. The plane of the vertical magnetization recording heads which faces the magnetic plane of the video tape is provided with a main magnetic pole and auxiliary magnetic pole, thereby causing at least one portion of the recording magnetic flux passing from the auxiliary magnetic pole to the main magnetic pole to penetrate the recording magnetic layer of the video tape at substantially right angles.
