Abstract
Summary form only given. A novel monolithic optical disk pickup head with four integrated free-space micro-optical elements has been realized by the surface-micromachined free-space micro-optical bench technology. A symmetric focused beam with FWHM width of 1.8 /spl mu/m is successfully observed. Because the pickup head is very compact (2 mm x 3.5 mm), it is possible to integrate multiple pickup heads on the same chip for parallel data access, or pickup head arrays with different focal length for multilayer optical data storage systems.
