A flying-type composite magnetic head includes (a) a magnetic core constituted by a pair of core pieces bonded together by a first glass portion, at least one of opposing surfaces of the core pieces being formed with a thin magnetic metal layer; (b) a non-magnetic slider having a slit for receiving the magnetic core; and (c) a second glass portion for fixing the magnetic core in the slit; the first glass portion having a softening point lower than a first bonding temperature by 70 DEG C. or more and a yielding temperature higher than a second bonding temperature, and the second glass portion having a softening point lower than a second bonding temperature by 70 DEG C. or more. The first bonding temperature T1 DEG C.) for forming the first glass portion satisfies the following relation: T1</=aW+b, wherein W is a thickness ( mu m) of the thin magnetic metal layer, a is between -25 and -15 and b is between 720 and 770, and a second bonding temperature T2 for forming the second glass portion is 530 DEG C. or lower. |
