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 head slider moveable relative to a storage media having a storage layer is disclosed. The disc head slider comprises a read head formed on the head slider, and comprises a first electrical contact layer adapted to carry a sensor current, a second electrical contact layer adapted to carry the sensor current, a read sensor and a bias magnet. The read sensor is configured to carry the sense current perpendicular to plane. The read sensor also has a top sensor edge, and has a bottom sensor edge aligned with the air-bearing surface to access data in the storage disc. The bias magnet magnetically biases the read sensor. Further, the first and second electrical contact layers are made of a material that does not magnetically shield the read sensor.

摘要： A method of recording information bits in a magnetic storage medium, the method comprising positioning a first conductor adjacent to a magnetic recording medium, the conductor having a width and a length, wherein a distance between the first conductor and the magnetic recording medium is less than or equal to the width and the length, and passing a first current through the conductor of sufficient magnitude to produce a magnetic field in the magnetic medium greater than one Tesla and having a magnetic field gradient in a cross track direction and a down track direction greater than 100 Oe/nm over a bit dimension. The thickness of the first conductor can be less than or equal to the distance between the first conductor and the magnetic recording medium. The current density in the conductor can be greater than 109 ampere/cm2, and the length of the conductor can be less than 100 nm. The current can be applied as one or more pulses in a predetermined clock cycle time. The magnetic field can be augmented by using an additional conductor, an adjacent ferromagnetic film, and/or a magnetic yoke and coil. Magnetic recording heads and disc drives that record data in accordance with the method are also included.
