Abstract: 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.

Abstract: 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.

Abstract: An information recording/reproducing apparatus of the invention is equipped with an objective lens, a light source and a variable optical element having a grating which demonstrates a piezo-electric effect by means of an electric field. The light source emits and irradiates a laser beam onto the grating to generate a 0th order diffraction beam and +/− 1st order diffraction beams in accordance with first order diffraction efficiency, and the objective lens converges the 0th diffraction beam and +/− 1st order diffraction beams which are irradiated onto an information recording medium for the purpose of information recording or information reproducing. By controlling an electric field applied to the grating, the first order diffraction efficiency of the grating is adjusted, whereby light beams are generated which have power levels appropriate for various kinds of information recording media.
