OPTICAL PICKUP, OPTICAL DISK DRIVE HAVING THE SAME, AND METHOD OF BONDING OPTICAL COMPONENT TO THE SUBSTRATE THEREOF

摘要

The substrate of a housing that holds a prism optical component has almost hemispherical recesses at positions that correspond to the four corners of the prism optical component. An adhesive that is fast dried is applied into the hemispherical recesses. To the back of the prism optical component, an adhesive that is cured with time or a thermosetting adhesive is applied, forming a thin layer having uniform thickness.
