<P>PROBLEM TO BE SOLVED: To provide an optical pickup device which appropriately records/reproduces information even when a light source unit including two light emitting parts is adopted, and even when change with time and environment change occurs, and to provide the light source unit. <P>SOLUTION: Since a light emitting part holder HD can be driven to an arbitrary position by an actuator, an axis line L2 of luminous flux of a second semiconductor laser LD2 mounted on the holder HD or an axis line L3 of luminous flux of a third semiconductor laser LD3 mounted thereon can be aligned with an optical axis of a condensing optical system of the optical pickup device shown in Fig.1, influence due to optical axis deviation of the light source therefore can be evaded. <P>COPYRIGHT: (C)2009,JPO&INPIT |
