Title (EN) METHOD FOR ADJUSTING POSITION OF OPTICAL ELEMENT
(FR) PROCÉDÉ D'AJUSTEMENT DE LA POSITION D'UN ÉLÉMENT OPTIQUE
(JA) 光学素子の位置調整方法
Abstract:
(EN) Provided is a method for adjusting the position of an optical element making is possible to improve connecting efficiency using simple adjustments, with consideration given to minimizing the size of a magnetic recording head. The method for adjusting the position of the optical element is used for adjusting the position of a magnetic recording head having: a light source for emitting light in a direction substantially orthogonal to an optical waveguide, on a slider having the optical waveguide; and an optical element having curvature only in a predetermined direction in a region where light is radiated from the light source, a reflective surface for reflecting light from the light source being formed in the optical element. The method for adjusting the position of the optical element has a positioning step and a fixing step. In the positioning step, the optical element is moved in one direction relative to the light source, and the optical element is positioned relative to the light source so that the light from the light source is concentrated on an incidence end of the optical waveguide by the reflective surface. In the fixing step, the light source and the optical element are fixed in a positioned state.
(FR) L'invention concerne un procédé permettant d'ajuster la position d'un élément optique, rendant possible l'amélioration de l'efficacité de connexion au moyen d'ajustements simples, en considérant la minimisation de la taille d'une tête d'enregistrement magnétique. Le procédé permettant d'ajuster la position de l'élément optique est utilisé pour ajuster la position d'une tête d'enregistrement magnétique ayant : une source de lumière permettant d'émettre de la lumière dans une direction sensiblement orthogonale à un guide d'ondes optique, sur une glissière comportant le guide d'ondes optique ; et un élément optique n'ayant une courbure que dans une direction prédéterminée dans une zone où la lumière rayonne de la source de lumière, une surface réfléchissante permettant de réfléchir la lumière de la source de lumière étant formée dans l'élément optique. Le procédé permettant d'ajuster la position de l'élément optique a une étape de positionnement et une étape de fixation. Dans l'étape de positionnement, l'élément optique est déplacé dans une direction par rapport à la source de lumière, et l'élément optique est positionné par rapport à la source de lumière de sorte que la lumière de la source de lumière est concentrée sur une extrémité d'incidence du guide d'ondes optique par la surface réfléchissante. Dans l'étape de fixation, la source de lumière et l'élément optique sont fixés dans un état positionné.
(JA)  磁気記録ヘッドのサイズの制約を考慮しつつ、簡易な調整で結合効率を向上させることができる光学素子の位置調整方法を提供する。光学素子の位置調整方法は、光導波路を有するスライダ上に、光導波路と略直交する方向に光を出力する光源と、光源からの光の照射領域において所定方向にのみ曲率を有し、光源からの光を反射する反射面が形成された光学素子とを有する磁気記録ヘッドにおける位置調整に用いられる。光学素子の位置調整方法は、位置決め工程と、固定工程とを有する。位置決め工程は、光源に対して光学素子を一方向に移動させ、光源からの光が反射面により光導波路の入射端に結合されるよう光源に対して光学素子の位置決めを行う。固定工程は、位置決めされた状態で光源と光学素子とを固定する。
