Abstract

PURPOSE: To make a head tolerant of external induction, to reduce a cross field, and also to eliminate an azimuth loss based upon the parallelism of gaps by joining front core parts for recording and reproduction together via a nonmagnetic body connected to the back surface of the block of them.
CONSTITUTION: To the back surface of the front core block where recording gap 113 and reproducing gap 213 are formed of three rectangular head core materials, non-magnetic material 600 with grooves 601W603 is bonded, and a tape sliding surface side is cut in a "W" shape and shield case insertion groove 301 is formed in the center of it. After slicing along a two-dot chain line, front cores 111 and 211 and non-magnetic body 60, and channel shield plate insertion grooves 131 and 231 are formed. Next, the top and reverse surfaces are lapped and rear cores 112 and 212 wound with a coil are joined to complete a head element.
