Abstract

PURPOSE:To improve a yield at manufacturing by exposing a first track groove formed at the tip of one side block by the height difference between both blocks onto the upper surface of other block while a core block is joined. CONSTITUTION:A height H1 of a core block 17 is higher than a height H2 of a core block 18 and the height of a core block 20 is the same as the height of the core block 18. In order to form a core assembly 24, blocks 17, 18 and 20 are prepared and track grooves 17a and 18a are formed at an equal interval on the protruded surface of blocks 17 and 18. Next, on the other side of a protruding surface, a thin film to constitute a recording and reproducing gap 3 is formed and next, the blocks 17 and 18 are joined by using a weld glass 19. Next, a second track groove 18b is formed and the block 20 is deposited by a weld glass 21. Further, the upper surface of the joining body is ground, a height difference is eliminated, a flat surface is obtained, and cutting is executed by cutting lines 22 and 23 and the core assembly 24 is obtained. To respective first cores 1 and 8 of the assembly 24, a bobbin to wind the coil is fitted and respective back cores are joined.
