摘要
A optical data processing apparatus included a light source, an optical system that concentrates light from the light source to an optical data storage medium, and a mechanism that scans the concentrated laser light on the optical data storage medium, the light source includes at least one Vertical-Cavity Surface-Emitting Laser (VCSEL) device that emits laser light, the at least one VCSEL device included an active region and a current-confined portion between first and second mirrors that form a vertical resonator structure, and an opening having a diameter equal to or larger than about 4 micrometers is formed in the current-confined portion for applying current.
