摘要：
A method to erase data stored on an erasable optical recording system is provided. The optical recording system includes a laser IO head having a blue-light laser, a red-light laser, and an infrared-light laser writing data on the blu-ray disc, the DVD disc, and CD disc, respectively. The method includes indexing the infrared-light laser of the laser IO head one track of the blu-ray disc every 0.4 revolutions after first 0.8 revolutions, to erase the data stored on the blu-ray disc.
