Abstract

PURPOSE: To manufacture long-life magnetic heads at low cost by coupling and bonding a head chip block of a magnetic material groove-worked with a part left to track width and a track-reinforcing block of a nonmagnetic material and then by cutting the obtained body after polishing its compound surface.
CONSTITUTION: Coupling block 15 with fixed track part 15a formed in a comb- tooth shape is formed by a known method. Track-part reinforcing block 17 made of a nonmagnetic material with longitudinal grooves 16 formed a little bit wider than the width of track part 15a is used here and coupled with coupling block 15 at intervals l5 between track part 15a and longitudinal grooves 16; and longer groove 18 of block 17 is provided with glass-based stick-shaped adhesive 19, which flows into each groove by heating to join blocks 15 and 17 together. Next, the top surface part is removed by arrow-directional cutting and polishing work for cutting as shown by detted lines, so that head chips 21 with joined reinforcing block pieces 17a and 17b will be obtained.
