Abstract
Provided is an optical recording head in which a light beam from a light source is collected by an optical element and reflected on a reflecting surface to be formed into a spot light. Since a support portion for supporting the light source of the optical element at a predetermined position and the reflection surface for reflecting the light beam are formed integrally with each other, it is not required to perform the positioning thereof, and light can be collected to a very small spot with high efficiency, and an optical recording head and an optical recording apparatus having low heights can be provided.
