Abstract

PURPOSE:To make the track height of both heads to equal to each other to make a cap slit parallel completely by fixing chip cores, which constitute recording and reproducing heads, onto a single shield block and inserting them into a shield case. CONSTITUTION:Recording chip core 3 and reproducing chip core 4 are caused to adhere onto recording and reproducing chip core positioning block 2, which has the parallel degree of upper and lower faces finished with a high precision, through spacer 5 on the basis of the back edge face side. Further, spacer 6 and shield block 7 are superposed onto them, and they are inserted to spaces 1a and 1b of shield case 1 having center partition 1c corresponding to cut grooves 2a and 5a of block 2 and spacer 5 under this state, and back core assembly 8 and terminal assembly 9 are fitted. Next, when the head front face is processed by polishing, the closed edge of grooves 2a ans 5a are opened to expose partition 1c in front, and the recording head and the reproducing head are independent of each toher.
