摘要： PROBLEM TO BE SOLVED: To provide an optical head device capable of preventing an optical axis from fluctuating even if environmental temperature changes. SOLUTION: When mounting a half mirror 41 as an element for separating an optical path for outgoing light and return light on a resin-made device frame 6 of the optical head, the half mirror 41 is temporarily fixed by a press spring 8. Next, after applying an epoxy adhesive 7 as a thermosetting adhesive between the upper face of the half mirror 41 and the device frame 6, the epoxy adhesive 7 is hardened by heat treatment. By this heat treatment, the residual stress is removed from the resin-made device frame 6. Thereafter, the other components are mounted on the device frame 6. For the press spring 8, it is removed after the epoxy adhesive 7 is hardened. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an optical head device capable of surely compensating TE offset caused when a 3-beam method is employed for detecting a tracking error signal.
SOLUTION: In the light receiving element 3 of the optical head device, a distance between the center positions of first and second sub-light receiving areas 32 and 33 is longer than that between the center positions of first and second sub-beam spots 52 and 53. Thus, when an objective lens 45 moves in a tracking direction, one of the sub-beam spots 52 and 53 approaches the center of the sub-light receiving center while the other sub-beam spot moves apart from the center of the sub-light receiving area and a part thereof protrudes. Consequently, since the light receiving level of the other sub-beam spot in the sub-light receiving area is reduced, TE offset can be compensated.

摘要翻译：要解决的问题：提供一种能够可靠地补偿当采用3束方法来检测跟踪误差信号时引起的TE偏移的光学头装置。解决方案：在光学头装置的光接收元件3中，第一和第二副光接收区域32和33的中心位置之间的距离长于第一和第二子光束的中心位置之间的距离点52和53.因此，当物镜45沿跟踪方向移动时，子光束点52和53中的一个接近副光接收中心的中心，而另一个子光束点离开中心的一部分突出。因此，由于子光接收区域中的另一个子光束点的光接收电平减小，所以可以补偿TE偏移。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To adjust an erecting mirror by using an autocollimator even in an optical pickup device of a finite optical system. SOLUTION: This is an adjusting method of the erecting mirror 2 of the optical pickup device 4 which is provided with a light source 1 and an erecting mirror 2 for changing the direction of the light emitted from the light source, and which is made up of the finite optical system 3. The erecting mirror 2 is adjusted by using an adjusting tool 5 for the erecting mirror 2, a collimator lens 6, and an autocollimator 7; attaching the optical pickup device 4 to the adjusting tool 5; attaching the collimator lens 6 to the adjusting tool 5 so that the exit light from the collimator lens 6 becomes parallel light when the erecting mirror 2 is adjusted to a predetermined position; and using the autocollimator 7 so that the exit light from the collimator lens 6 becomes parallel.
