摘要： A combined read/write magnetic head is disclosed in which the read head includes a magnetoresistive element (MRE) overlying a substrate of substantially magnetically impermeable material, a broken (discontinuous) flux guide overlying the MRE and a continuous flux guide overlying the broken flux guide. The write head of the combined read/write magnetic head overlies the read head and shares the continuous flux guide with the read head, the continuous flux guide serving as a bottom pole of the write head. Significantly, the dimensions of the various elements of the combined read/write magnetic head are chosen so that relatively little magnetic flux produced by the write head during writing, or entering the write head during reading, is communicated via the shared flux guide to the MRE.

摘要： Abrasive grain including manganese oxide therein are provided. The inclusion of manganese oxide can be utilized to reduce the transition temperature of transitional alumina(s) to alpha alumina(s), during the formation of the abrasive grain. Further, manganese oxide presence can be utilized to generate sintered abrasive grain having a submicrometer, faceted microstructure. The abrasive grain are useful in abrasive articles such as coated abrasives, three-dimensional, low density abrasives, and bonded abrasives.

摘要： A balanced bi-directional current source is provided, which includes first and second current output terminals, a current control circuit, first and second amplifiers and first and second sense impedances. The current control circuit has a reference input, a feedback input, and a control output, which is based on the reference input and the feedback input. The first amplifier has a first amplifier input, which is coupled to the control output, and a first amplified output. The second amplifier has a second amplifier input, which is coupled to the control output, and a second amplified output, which is inverted relative to the first amplified output. The first sense impedance is coupled in series between the first amplified output and the first current output terminal and has a feedback output which is coupled to the feedback input. The second sense impedance is matched with the first impedance and is coupled in series between the second amplified output and the second current output terminal.
