    摘要： A magnetic recording playback head and a method for producing the same having an improved wear resistance and resistance to chipping as well as an improved production rate. The head is formed from a pair of magnetic cores joined through a gap-forming film. The lateral sides of the gap are flat, except for the surface repair to contact the tape, which have a width equal to the track width. The flat sides are coated with a nonmagnetic thin hard film of a material such as alumina or titanium nitride.

    摘要： Provided are a brushless motor control device and a brushless motor system capable of preventing impossibility of intended control of a brushless motor resulting from false recognition that the brushless motor is in operation in spite of stoppage of the brushless motor. A brushless motor control unit calculates a voltage instruction, representing voltages to be applied to the brushless motor, according to a control instruction supplied from an upper control device. A position error calculation unit calculates and estimates a position error between d-q-axes and dc-qc-axes as rotational coordinate axes by use of the voltage instruction outputted by the brushless motor control unit, current values acquired by a coordinate transformation unit and revolution speed for control of the brushless motor. A fault detection unit judges whether the brushless motor is faulty or not based on the position error calculated by the position error calculation unit.
