Abstract
PURPOSE: To obtain the said reproduction head suitable for video tape recorder and excellent in the video quality, by decreasing the width of reproduction gap than that of recording gap.
CONSTITUTION: The center core block 11 of plate shape is bonded with the C type core block 10A such as ferrite, and the recording gap 12 is formed between the tip of the C type core block 10A and the center core block 11 with the gap member like glass. Next, a plurality of separating grooves 13 are formed on the C type core block 10A, and the C type core block 10B symmetrical with block 10A and formed with a plurality of separation grooves 15 is bonded to the C type core block 10A. In this case, between the tip of the C type core block 10B and the center core block 11, the reproduction gap 16 parallel to the recording gap and 1/3W1/80 in width is formed, allowing to obtain the magnetic recording and reproduction head.
