Combining Data Detection using Pattern Recognition (DDPR) with LSB (Least Significant Bit) Limited Modulation (LLM) effectively reduces data errors in a blue laser optical disc system. We confirmed that a recording capacity of 25 GB is feasible for a system by using a laser diode of 405-nm wavelength and a 0.65 numerical aperture objective lens was effective to reduce data errors in a blue laser optical disc system.
