摘要： An image composing apparatus includes a first accumulator which repeatedly accumulates a moving amount of an imaging surface in one of a horizontal direction and a vertical direction. A first determiner repeatedly determines whether or not a movement of the imaging surface in another of the horizontal direction and the vertical direction satisfies a taking condition, in a period during which an accumulated value of the first accumulator belongs to a predetermined range. A second determiner repeatedly determines whether or not the accumulated value of the first accumulator reaches an upper limit of the predetermined range. A taker takes, for image composing, a scene image produced on the imaging surface corresponding to updating from a negative result to a positive result on a determined result of the first determiner and/or the second determiner. A restarter restarts the first accumulator in association with a taking process of the taker.

摘要： An MR element in a CPP structure includes a spacer layer made of Cu, a magnetic pinned layer containing CoFe and a free layer containing CoFe that are laminated to sandwich the spacer layer. The free layer is located below the magnetic pinned layer. The free layer is oriented in a (001) crystal plane, the spacer layer is formed and oriented in a (001) crystal plane on the (001) crystal plane of the free layer. Therefore, in a low resistance area where an area resistivity (AR) of the MR element is, for example, lower than 0.3 Ω·μm2, an MR element that has a large variation of a resistance is obtained.

摘要： A recording element supported by a slider includes a non-magnetic film and a magnetic pole film. The non-magnetic film has a depression whose inner surface is provided with an amorphous electrode film used as a plating seed film. Above the electrode film, the magnetic pole film is grown by plating. The magnetic pole film may be either an electroplated film grown on the electrode film to have a maximum crystal grain size of 20 nm or less or an electroless plated film. This decreases coercive force of the magnetic pole film.

摘要： A pole layer incorporates a track width defining portion and a wide portion. The track width defining portion has an end face that is located in the medium facing surface and that defines the track width. The maximum width of the wide portion is greater than the track width and equal to or greater than the length of the wide portion taken in the direction orthogonal to the medium facing surface. When the coil is generating no magnetic field, in the end face of the track width defining portion, there exist first and second regions in which the directions of components of magnetization orthogonal to the medium facing surface are opposite.
