发明名称 MANUFACTURE OF MAGNETIC HEAD
摘要 PURPOSE:To easily and cheaply form an insulating film and prevent occurrence of defective insulation due to electric contact between a magnetic core and a coil and consequent shortening of life of a magnetic head by forming the insulating film by vapor depositing an insulating material on winding sections in the state of a core block. CONSTITUTION:Winding sections 1a and 2a are pierced in a pair of right and left core blocks 11 and 12, and at the same time, a winding groove 1b is formed on the face opposite to the winding section 1a of a core block 11. Then, an insulating material such as SiO2 etc. is vapor deposited on the face including winding sections 1a and 2a of the two core blocks 11 and 12 to form insulating films 3. Successively, the winding groove 1b is filled with an insulating material such as glass etc. Then, the butted faces 1c and 2c of core blocks 11 and 12 are polished and core blocks 11 and 12 are bonded and unified at the butted faces 1c and 2c through a bonding agent such as glass etc. to form a coupled core block. The coupled core block is cut along a cut line shown by an alternate long and short dash line to form a magnetic head assembly.
