Abstract
PURPOSE: To prevent defective adhesion, breakaway, etc., caused by bubbles generated in filling gas, by combinationally using glass low in softening degree and high glass in glass adhesion and charging processes for core blocks constituting a magnetic head.
CONSTITUTION: In one head core block 9, notch grooves 11 for limiting track width parts 10 and groove 12 for a winding window are provided and non-magnetic layer 13 for obtaining gap width is formed. In the other block 6, notch parts 8 are made leaving track width 7 at one ridge part. Next, blocks 6 and 9 are butted with track width parts down and on graphite receptacle 15, filling glass bars, one for glass 14 low in softening point and the other for glass 16 low in softening point, are both placed. A difference in softening point should be from 50W100°C. The diameter ratio of glass bar 14W16 is preferably 2:1. As a result, glass bar 16 fuses by heating to wet a bonded surface first and as the temperature rises, bubbles in the void between the bonded surface and glass are removed; and the temperature further rises and when glass 14 also fuses, both glass parts are made into one, thereby finishing filling.
