发明名称 Tracking and focussing functions in optical disk apparatus
摘要 In optical apparatus for reading, writing or erasing optical disks, the optical head is implemented in integrated form. Silicon optical bench technology, including integrated optical waveguides, Y-splitters and directional couplers, is used in the design of the tracking, lens focussing, and read/write/erase functions.
