A DUAL CAPPING LAYER UTILIZED IN A MAGNETORESISTIVE EFFECT SENOSR
The present disclosure generally relates to a read head sensor in a magnetic recording head. The read head sensor comprises a dual capping layer in a sensor stack that may reduce magnetic coupling so as to enhance magnetic bias field, e.g., domain control, in the read head sensor. Furthermore, an up...

| description | The present disclosure generally relates to a read head sensor in a magnetic recording head. The read head sensor comprises a dual capping layer in a sensor stack that may reduce magnetic coupling so as to enhance magnetic bias field, e.g., domain control, in the read head sensor. Furthermore, an upper shield with multiple film stack having different film properties may also be utilized to enhance bias field generated to the read head sensor. Additionally, a coil structure may be positioned adjacent to a side shield to enhance bias field generation in the read head sensor. |
