Abstract

PURPOSE:To enable to record the information of video signal toward tape broadwise, by providing the magnetic path forming part consisting of the rotary head having magnetic substance head piece, fixed head opposing to the circumference surface and magnetic path forming part of magnetic substance to enable to magnetize the tape toward thicknesswise. CONSTITUTION:The rotary head A turned with the rotary shaft B has the rotary body of non-magnetic substance and the magnetic heads H1-HN provided so that the circumference direction is divided into N equally, the magnetic flux path is formed between the head pieces H1 and H4, and also the magnetic path can be formed also between the head pieces H2 and H3. The fixed head D consists of the fixed head 15 and magnetic flux path formation part 16, the head 15 is formed with the core 151 and the coil 152, and the core is formed with the exciting magnet incorporated with the magnetic path forming part 16. This excitation magnet is approximately of C-shaped type, and it is provided at the gap 17 so that a part of the circumference surface of the rotary head A can be clipped from axial direction with space.
