【発明の名称】磁気ヘッド、磁気ヘッドアセンブリ及び磁気ヘッド製造方法
Document Type and Number:
Japanese Patent JP2509387
Kind Code:
B2
Abstract:
A magnetoresistive (MR) sensor (20) is centre tapped to provide the difference signals for servo operation on data and sum signals for the data information. The centre-tap (14) of the MR sensor is made of a high resistivity material compared to the resistivity of the MR element itself such as tantalum, Nichrome and carbon. Processes which can be used to produce the high resistivity centre-tap conductor include an insulator layer to define both the track width and the centre-tap conductor and a sequence which first patterns the MR sensor and then masks to define the conductor regions.
