摘要： A compact read/write head having a biased giant magnetoresistive sensor. Permanent magnet films are placed adjacent to the giant magnetoresistive sensor operating in the current-perpendicular-to the-plane (Cpp) mode and spaced with respect to the sensor by conducting films. These permanent magnet films provide a magnetic bias. The bias field is substantial and fairly uniform across sensor height. Biasing of the giant magnetoresistive sensor provides distinguishable response to the rising and falling edges of a recorded pulse on an adjacent recording medium, improves the linearity of the response, and helps to reduce noise. This read/write head is much simpler to fabricate and pattern and provides an enhanced uniformity of the bias field throughout the sensor.

摘要： A ferromagnetic shield material having a minimized anisotropic magneto-resistance effect permits the use of a combined shield/electrical lead for magneto-resistive read elements. The shields/electrical leads may therefore be placed closer together, maximizing the recording density that may be read by a magnetic recording head using a read element having such shields/leads.

摘要： A magnetic transducer employs a giant magnetoresistive sensor whose sensing surface is separated by a dielectric layer from a magnetically recorded surface carrying recorded data signals to be read back by the transducer. The dielectric layer serves to protect the sensing layer from corrosion, electrostatic discharge from the record surface, mechanical damage from asperities, thermal asperities from heating resulting from close contact between the transducer and the record surface, and damage from exposure during lapping operations. This structure also reduces the readback pulse width and offtrack assymmetry, and improves servo linearity, thereby increasing recording density. The reduced signal amplitude is compensated for by the use of a giant magnetoresistive transducer with an intrinsically large output. The use of the recessed transducer reduces saturation of the transducer due to the record medium flux at reduced signal amplitudes, thereby increasing readback efficiency.
摘要翻译：磁传感器采用巨磁电阻传感器，其感测表面由介质层与磁记录表面分开，承载记录的数据信号，由传感器回读。电介质层用于保护感测层免受腐蚀，记录表面的静电放电，粗糙度的机械损伤，由传感器和记录表面之间的紧密接触导致的加热产生的热不均匀性以及研磨操作期间曝光造成的损坏。这种结构还减少了回读脉冲宽度和偏移不对称性，并且提高了伺服线性度，从而提高了记录密度。降低的信号幅度通过使用具有固有大输出的巨磁阻换能器来补偿。凹陷传感器的使用由于信号幅度减小的记录介质通量而降低了传感器的饱和度，从而提高了回读效率。

摘要： Magnetic transducers are formed with common magnetic exchange layers capable of providing assertive and complementary signals. The transducers include an assertive transducer portion and a complementary transducer portion. Between the two transducer portions is a common bias portion which comprises an antiferromagnetic layer providing bias fields in different directions to the respective transducer portions. During normal operations, a current is directed into each of the transducer portions. The assertive transducer portion, being magnetically biased in one direction, generates a varying voltage as an assertive version of the electrical signal. The complementary transducer, being magnetically biased in another direction, generates another varying voltage as a complementary version of the electrical signal. In one embodiment, the transducer portions are implemented to operate as an anisotropic MR(AMR) sensor. In a second embodiment, the transducer portions operate as a giant MR(GMR) or spin valve sensor.
