延误源于缺乏供应的蓝色激光二极管，关键的组成部分，以便读取头的蓝光驱动器，这将是标准在每一个PS 3的单位。
The delay stems from a lack of supply of blue-laser diodes, the crucial component for the read-head of the Blu-ray drives, which will be standard in every PS3 unit.
该驱动器保持高精度激光二极管电流或稳定的光电二极管电流调整。
The driver maintains precision laser diode current or stable photodiode current regulation.
