| 英文摘要 | A dual beam laser array provides two overlapping beams for use in a direct read after write (DRAW) optical data storage system. A first portion of the overlapping beams is directed to a first optical detector and a second portion of the overlapping beams is directed to a second optical detector. A logic circuit connected to the optical detectors generates power signals representative of the power levels of each of the overlapping beams without the need to completely separate the beams. |
