摘要： Tolerances for manufacturing reader structures for transducer heads continue to grow smaller and storage density in corresponding storage media increases. Reader stop layers may be utilized during manufacturing of reader structures to protect various layers of the reader structure from recession and/or scratches while processing other non-protected layers of the reader structure. For example, the stop layer may have a very low polish rate during mechanical or chemical-mechanical polishing. Surrounding areas may be significantly polished while a structure protected by a stop layer with a very low polish rate is substantially unaffected. The stop layer may then be removed via etching, for example, after the mechanical or chemical-mechanical polishing is completed.

The probe head (100) includes a sensor unit having: as sensor (140) which records or reads data on or from a predetermined medium (200); first (120) and second (180) shields disposed on both sides of the sensor (140) at a predetermined distance from each other; and first (130) and second (150,170) intermediate layers respectively interposed between the sensor (140) and the first shield (120), and the sensor (140) and the second shield (180). The method includes: providing a substrate (101); forming an insulating layer (110) on the substrate; forming a first shield (120) on the insulating layer (110); forming a first intermediate layer (130) on the first shield (120); forming a sensor (140) on the first intermediate layer (130); forming a second intermediate layer (150,170) on the sensor; forming a second shield (180) on the second intermediate layer (150,170); and forming a protective layer (190) on the second shield (180). Accordingly, the resolving ability and sensitivity of the probe head (100) can be simultaneously improved, and the probe head (100) can be easily manufactured.

摘要： A head (10) is provided for reading and writing to tape media (48) along a tape head face. The tape head comprises a plurality of modules, each module comprising a read element (54) and a write element (52) spaced apart and terminating at the tape head face and formed over a substrate (12). The read element comprises a soft film bias layer (24) and a hard film bias layer (25) butted against the SFB layer. The write element comprises two pole tips (14,16) spaced apart by a gap (22). The tape head further includes a plurality of activating conducting coil turns (20) operatively associated with the write element and covered by a cross-linked photoresist and positioned between the gap and one of the pole tips and set back from the tape head face. The tape head has at least one of the following elements: (a) a wear shield (34) between the read element and the write element for limiting wear of the gap between the two pole tips, the wear shield being grounded for decoupling read and write functions of the tape head, for allowing same module read/servo/write functions simultaneously, and for grounding static charge from the tape media; (b) a layer of electrically conductive and corrosion-resistant material (62), such as rhodium, under the hard film bias layer to reduce its resistance; and (c) a non-activating dummy coil turn (120,220) closer to the pole tips than the activating coil turns for defining a forward termination of the cross-linked photoresist (38a) between the activating coil turns and the tape head face to thereby provide improved ease of processability.
