PURPOSE:To obtain a thin film magnetic head having a good high frequency characteristic, good linearity and a wide dynamic range by providing a magnetic resistance effect element (MR element) near a magnetic flux introducing path (yoke) continuously formed without having a divide part. CONSTITUTION:An MR element 7 is formed in an insulator 11 at a process to laminate it in the order of an insulator/an MR element/an insulator on a lower part yoke 9. On the insulator 11, an upper part yoke 8 to introduce a magnetic flux to the MR element 7 is overlapped and the upper part yoke 11 is connected with the lower part yoke 9 in a side mutually facing with a head gap and formed in a continuous body. Namely, since the MR element 7 is arranged near the yoke 8, a signal generated in the yoke 8 can be detected even in the MR element 7 and for the yoke 8 facing with the MR element 7, it is not necessary to provide a gap such as a conventional head. Thus, without damaging a function as a magnetic head, the magnetic circuit resistance of the whole head can be reduced, the high frequency characteristic can be improved and also the linearity of the head and a dynamic range are improved. |
