摘要： An optical head device includes a light source (30) configured to emit a light beam, a light collecting optical system configured to converge the light beam onto an information recording medium (10), a hologram element (20) configured to diffract the light beam reflected from the information recording medium (10), and a photodetector (40) having a plurality of detection regions configured to receive the light beam diffracted by the hologram element (20). The hologram element (20) has two diffraction regions (261 and 262) separated from each other by a straight line (260) extending in a radial direction of the information recording medium (10). At least one of the two diffraction regions has a pattern which introduces coma aberration in the radial direction. The light diffracted by the diffraction region having the coma aberration has coma aberration in the radial direction.

摘要： An optical pickup includes a hologram element divided into four regions in a direction parallel to a tracking direction of an optical information recording medium and a direction perpendicular thereto. The hologram element allows two pairs of diffracted lights from two paired regions adjacent in parallel with the tracking direction to be made incident into light receiving elements so as to align in the direction perpendicular to the tracking direction.

摘要： An electronic module includes a board unit having a handle and a module housing. The handle includes a grip portion and a pair of leg portions. The leg portions have engagement convex portions extending from portions serving as rotary pivots, of the leg portions. The module housing includes an engagement concave portion provided to correspond to the engagement convex portions. When the board unit is inserted into the module housing, by rotating the handle around the rotary pivots in a direction along which the grip portion approaches the panel portion, the engagement convex portions are brought into contact with a part of the engagement concave portion to produce a force in a direction, along which the board unit is pressed into the module housing.
