Patent number: 8333898Abstract: A method for manufacturing a magnetic tape head having a data sensor and a servo sensor. The data sensor and servo sensor are each separated from first and second magnetic shields by a non-magnetic gap layer, and the gap thickness for the servo sensor is larger than the gap thickness for the data sensor. The method involves depositing a first gap layer over shield structures, then depositing a second gap layer using a liftoff process to remove the second gap layer over the data sensor region. A plurality of sensor layers are then deposited, and a stripe height defining mask structure is formed over the data and servo sensor regions, the mask having a back edge that is configured to define a stripe height of the data and servo sensors. An ion milling is then performed to define the stripe height and to remove gap material from the field.Type: GrantFiled: December 20, 2010Date of Patent: December 18, 2012Assignee: Hitachi Global Storage Technologies Netherlands B.V.Inventors: Diane L. Brown, Quang Le, Chang-Man Park, David J. Seagle, Eileen Yan

Patent number: 8296930Abstract: A method for manufacturing a magnetoresistive sensor that results in the sensor having a very flat top magnetic shield. The process involves depositing a plurality of sensor layers and then depositing a thin high density carbon CMP stop layer over the sensor layers and forming a mask over the CMP stop layer. An ion milling is performed to define the sensor. Then a thin insulating layer and magnetic hard bias layer are deposited. A chemical mechanical polishing is performed to remove the mask and a reactive ion etching is performed to remove the remaining carbon CMP stop layer. Because the CMP stop layer is very dense and hard, it can be made very thin. This means that when it is removed by reactive ion etching, there is very little notching over the sensor, thereby allowing the upper shield to be very thin.Type: GrantFiled: December 22, 2009Date of Patent: October 30, 2012Assignee: Hitachi Global Storage Technologies Netherlands B.V.Inventors: Shin Funada, Quang Le, Thomas L. Leong, Jui-Lung Li, Chang-Man Park, Ning Shi, Hicham M. Sougrati

Publication number: 20120156390Abstract: A method for manufacturing a magnetic sensor that result in improved magnetic bias field to the sensor, improved shield to hard bias spacing and a flatter top shield profile. The method includes a multi-angled deposition of the hard bias structure. After forming the sensor stack a first hard bias layer is deposited at an angle of about 70 degrees relative to horizontal. This is a conformal deposition. Then, a second deposition is performed at an angle of about 90 degrees relative to horizontal. This is a notching deposition, that results in notches being formed adjacent to the sensor stack. Then, a hard bias capping layer is deposited at an angle of about 55 degrees relative to horizontal. This is a leveling deposition that further flattens the surface on which the top shield can be electroplated.Type: ApplicationFiled: December 21, 2010Publication date: June 21, 2012Applicant: Hitachi Global Storage Technologies Netherlands B.V.Inventors: Satoru Araki, Shin Funada, Insik Jin, Quang Le, Simon H.
