摘要： PROBLEM TO BE SOLVED: To prevent an optical head which can obtain a stable servo signal in recording and reproducing of a multi-layer optical disk. SOLUTION: The optical head is provided with a division element having a plurality of regions. The division element can divide luminous flux reflected by the optical disk into a plurality of luminous flux whose exiting directions are different. When focus is adjusted to the target information recording layer of the optical disk, the reflected luminous flux from the target information recording layer is focused on the light receiving part of a photodetector, then respective regions of the division element and the light receiving part of the photodetector are constituted so that the light receiving part of the photodetector is not irradiated with reflected luminous flux from the information recording layer other than the target information recording layer.

摘要： PROBLEM TO BE SOLVED: To solve the problem that productivity is bad because chucking work of an adjustment holder is manual work to make it difficult to shorten a standard time (ST) of a step because a worker has to grab a hanging photodetector and plate with a tool, such as tweezers to chuck the photodetector and the plate to the adjustment holder in the step for position adjustment and adhesion of the photodetector.SOLUTION: A standby position of a photodetector is configured to be able to be pressed in the direction of an optical pickup by reaction force of a flexible substrate so as to roughly stabilize the standby position of the photodetector, and be subjected to sliding suppression so as to prevent deviation from occurring on a surface on which an optical pickup housing is brought into contact with a plate.
