Error analysis and tolerance allocation method for the optical head of Near-Filed Recording (NFR) system are presented. After design and fabrication of NFR system, the performance test for the NFR system is done. Using the optical simulation program, CODEV, the assembly and manufacturing tolerances of the NFR optical head are simulated. The tolerances analysis result shows that the tolerance is very tight. So we propose optimal compound tolerance allocation method using WOW (worst on worst) analysis, RSS (root sum square) analysis and Monte-Carlo analysis.
