摘要： The present invention intends to solve the above described problems and provides a high reliability complex type thin film magnetic head in which high recording magnetic field density is achieved without deteriorating an MR element by heat, and in the case when the complex type thin film magnetic head is of sliding type, eccentric friction likely to occur in a lower magnetic core and a upper magnetic core is relaxed and production method thereof. The complex type thin film magnetic head is structured by forming an MR head portion on an inductive head portion produced on a base substrate. Conductive coils are formed on the recess portions formed on the lower magnetic core because the groove portions exist through a first flattening layer.

摘要： It is assumed that W1 is the width for an end face of the lower magnetic shield thin film 4 which is exposed outward from the tape sliding surface 1a. It is also assumed that W2 corresponds to the sum of the width for an end face of the MR element 7 which is exposed outward from the tape sliding surface 1a and widths for end faces of a pair of ferromagnetic films 9 and 10 which are exposed outward therefrom. The width W1 is determined to be smaller than W2. When the MR head 1 is mounted on the head support plate 30 or the rotary drum 42, it is possible to use as a marker the lower magnetic shield thin film 4's end face exposed from the tape sliding surface.
摘要翻译：假设W1是从磁带滑动面1a向外露出的下磁屏蔽薄膜4的端面的宽度。还假定W2对应于从带滑动表面1a向外暴露的MR元件7的端面的宽度和一对暴露于外侧的一对铁磁性膜9和10的端面的宽度之和由此。宽度W1被确定为小于W2。当MR头1安装在头部支撑板30或旋转鼓42上时，可以使用从磁带滑动面露出的下部磁屏蔽薄膜4的端面作为标记。

摘要： A magnetoresistance effect magnetic head which is capable of shortening shield gap distance and which can be manufactured by a small number of manufacturing steps, and a manufacturing method therefor are provided. The magnetoresistance effect magnetic head having a magnetoresistance effect magnetic device held between a pair of soft magnetic members through insulating layers and conductors connected to the magnetoresistance effect magnetic device is structured such that the conductors are embedded in grooves formed in the insulating layer. Since the magnetoresistance effect magnetic device has the structure such that the conductors connected to the magnetoresistance effect magnetic device are embedded in the grooves formed in the insulating layer, the shield gap distance can be shortened.
