Abstract:
An optical pickup device includes a first optical system and a second optical system. The first optical system and the second optical system each include a mirror member that reflects light from a light source to change a direction of propagation of the light to a direction substantially perpendicular to the information storage surface of an optical disc. The first optical system and the second optical system are arranged such that a direction in which light from a first light source enters a first mirror member is substantially perpendicular to a direction in which light from a second light source enters a second mirror member.
