Magnetoresistive effect composite head |
摘要 |
An ID head is formed after a MR head is formed. An upper shield far from a substrate is a first magnetic pole. A nonmagnetic insulator existing through a magnetic gap on the first magnetic pole determines zero throat height, thereby specifying a recording track width of less than 2 mu m. The ID head comprises a front end portion of a second magnetic pole, which is exposed to ABS and partly rides over the nonmagnetic insulator, a nonmagnetic insulator for burying a step by the front end portion, a coil which is formed on the nonmagnetic insulator and covered with a nonmagnetic insulator, and a main body portion of the second magnetic pole formed so as to ride over the coil and front end portion. As a result, it is possible to solved various problems of the ID head in which the front end portion of the second magnetic pole is formed first to realize a narrow track width.
