Abstract
PURPOSE: To achieve higher production yield, stabler quality, better high frequency characteristics and higher abrasion resistance by specifying the production process of the video head and firmly forming the gap of high accuracy.
CONSTITUTION: First grooves 3, 4 of V-shape which become glass stoppers are formed on the top surfaces of rectangular parallelopiped blocks 1, 2 of high magnetic permeability ferrite, and a plurality of inclinded second grooves 5, 6 are formed on the outer edge of the top surfaces. After molten glass 9, 10 has been filled in the grooves 3 thru 6, third grooves 11, 12 which become winding windows are provided by parting the grooves 5, 6. Next, the top surfaces are finished to a mirror surface and non-magnetic materials 13, 14 are filmed so that the sum of their thicknesses t1, t2 become roughly equal to the gap width, after which, the blocks are contacted and are so adjusted that the width α of the base parts 7, 8 becomes equal to the track width. In this state the blocks 1, 2 are bound by heating in an inert gas atmosphere, whereby a front gap A and a rear gap B are created at the front and near of the grooves 11, 12. Next, the blocks 1, 2 are cut, whereby a discrete head 15 is obtained.
